Thanks to Hollywood films, good infrastructure and a magnificent landscape, overland holidays in the US are, and always will be incredible popular.
Stretching from its chilly border with Canada down to tropical Mexico and incorporating thousands of small towns and mega-metropolises along the way. There's more variety in this vast country than the pick and mix counter at Woolworths.
But if you're planning an overland holiday in the US you have a dilemma to face, to rough it or to road it?
With options ranging from deluxe 35-foot motorhomes complete with satellite TV and dishwasher to the back seat of a public bus, you're spoilt for choice when it comes to getting from A to B.
Before you set off decide what it is you want from your overland holidays. Is it an easy life, cruising the highways and byways in relative luxury? Is it value for money, as you try to see as much as possible on a tight budget? Or do you want complete freedom over your destination and the music you play on the stereo?
If it's luxury you're after, you couldn't get better than a top-of-the-range motorhome. Available for hire throughout the US, RVs allow you to travel with all of your home comforts, including the kitchen sink.
Although they may be more expensive to hire, motorhomes can actually save you a bit of money by cutting down on accommodation costs. Although any savings will probably be cancelled out by the hefty fuel costs.
Taking a step down the price ladder is the tried and tested car option. You may not have a built-in washing machine on hand, but driving a good old American automobile across the country is a once-in-a-lifetime experience.
With almost complete freedom over your itinerary, cars can give you as much or as little comfort as you want. Many hire companies now allow you to return your vehicle to a different city than you picked-up from, making cross-country odysseys even easier.
With plenty of destinations on offer but a lot less legroom, is that classic of American budget travel, the Greyhound bus. With a network covering pretty much the entire country travelling by bus gives you the freedom of travel without responsibility. With no need to worry about insurance, parking fines or petrol stations you can simply book your ticket, pack up your bag and go.
Though not exactly glamorous and definitely on the rougher end of the scale, there is a certain romance about travelling by bus. Although you may need some reminding of this after 15 hours sat next to the loos.
If you really want to rough it, the cheapest option is of course to hitchhike. Long the stuff of horror films and nightmares, the internet has revolutionised the way that hitchhikers operate.
Websites now offer a forum for drivers with empty seats and travellers with empty pockets to safely arrange travel plans. Making life safer and easier for all concerned.
