A giant, jester of a saguaro looks down on us as we delve into the desert once more along Signal Road.

Our plan: to skirt north of Alamo Lake towards Parker, on the Californian border, following desert dirt tracks. To Nancy's iPhone and Googlemaps we add photos taken of a detailed area map, sourced in a friendly ranch.

Here, the landscape feels broader, more open. As ever, there's no shortage of characterful cacti to keep us company, like this cholla, with its prickly, pudgy little fingers.

A taster for what lies ahead: the mystical Joshua Tree. We join the party and camp amongst them.

This swathe of desert is known for the mock airforce dogfights, and the evening air is patterned and streaked with vapour trails. Later, shrouded by the darkness of night, two jets thunder low overhead, hugging the contours of the land.

It's never easy figuring out which route is best to take. We were advised to detour off the wide, bladed dirt road that turns south to Lake Alamo, following instead the easily navigated powerline that runs due west from Baker Well. Our last experience with powerline shortcuts involved improbably steep descents, answered with impossibly steep climbs. Would this be a repeat scenario?

Yep... Though thankfully only a few humpbacks to deal with this time.

Then the track calms down a little, as it guides us through corridors of saguaros.

Around us, the craggy Rawhide and the Buckskin mountains poke up into the hazy sky.

The trail dipped ever upwards and downwards, pin-balling us along a ridge into the open desert.

For the most part, there was little sand to contend with. Only Mojave Wash provided a challenge, culminating in a sandy push onto the otherwordly, Planet Ranch Road.

How many locks does it take to close a gate?

Taking a break amongst the cottonwoods.

Later, the Tout Terrain Mule falls foul of a dastardly goat head spine. Luckily 20in tyres are quick and easy to repair - I should really have filled it with latex sealant like the rest of our tyres.

Finally, desert trails peter out and become a strip of oh-so-smooth pavement once more, for the last few miles into Parker...

...which, at first glance, didn't seem so appealing.

Old dinosaurs line the road in, like this square-jawed Cadillac.

With its strip of big box stores, gas stations, gun shops, desert buggies and goliath RVs, I can't say Parker really won us over...

Nor, being November 25th, were we expecting much in the way of Thanksgiving lunches. But glinting like a culinary jewel amongst the Pizza Huts and McDonalds of its dusty main strip, we chanced upon Cyber d'Lites, purveyors of both tasty cakes and fast wifi - a fine combination indeed. Thanks to the wonders of online banking, Nancy's mum treated us to a slap-up Thankgiving meal, rounded off with a piece of a Pumpkin Pie. Our bellies suitably ballooned, Tracey and Darlene sent us off with enough leftovers for a hearty dinner too, throwing in a giant muffin to tip us over the edge.

But the cyclist's appetite can never truly be quenched... By the next morning, we were ready for more sustenance. The Early Bird Cafe provided the perfect backdrop.

Trinkets cluttered every shelf, and framed posters of Elvis, John Wayne and Betty Boop adorned the walls. 80s hairstyles and waitress banter (What will it be, baby?) provided the final touches.

We go for a classic: pancakes, maple syrup, scrambled eggs, hash brown and crispy bacon... The All American Diner Experience.

Feeling in need of a shower, we bargain ourselves a room in the local Motel 6, a few doors down from Stan, who zips around in his electric wheelchair, trapping us to recount stories of his lap-dancing girlfriend. $40 gets us some classy digs with a view of the Pepsi machine, to the sound of Mexican ballads blasting out from the neighbour's truck.

Then, it's time to hit California! 'London Bridge' takes us over the Colorado River, the border between the two states.

We roll through the blink-and-you-miss-it settlement of Earp, named after Wyatt, the lawman/gunman/gambler famed for his part in the gunfight at the OK Coral. His only local legacy seems to be the talking puppet at the gas station - which, just like the one in 'Big', doesn't even seem to be plugged in. I listen to it try and goad me to 'empty ma pockets' into the slot and be regaled by Wyatt's 'wild west adventures.'

Then it's back out into the scrub, heading towards the aquaduct trail that runs west, parallel to the highway, at the foot of the mountains.

More sentinel powerlines keep us on track.

This being the thanksgiving festivities, it's also a chance to experience some good, wholesome American fun. Like a scene from a Mad Max movie, dune buggies and goggle-clad scrambler riders come screeching out of the hills, offering a cheery wave as they coat us in dust.

Who ever said the desert was flat?

Finally, we emerge at the forlorn Vidal Junction, camping in a scruff of land by the highway. Next stop, Joshua Tree...
