Getting to the Salt Flats is way easier than it was in 1860.
The Bonneville Salt Flats, and the Bonneville Speedway are located just 6 miles East of Wendover UT/West Wendover, NV. The nearest Metro area is Salt Lake City, UT 120 miles to the East.
The drive from Salt Lake to the Bonneville Speedway where the race starts is entirely freeway, and maintianing 75 MPH is no problem, so the drive takes under 2 hours.
If you are flying in, book your flight to Salt Lake City International Airport (SLC), rent a car, and drive West on Interstate 80 directly from the Airport. There are several hotels in the Wendover area, both on the Utah side, and the Nevada Side, including five Casinos.
The motels on the Utah side of the state line are generally pretty affordable if booked online, but as I've learned the hard way, don't call them directly as their direct rate is often $20 more per night.
Of course, you can always stay at one of the Wendover Casinos if you want that little taste of Vegas!
You are also more than welcome to car-camp on the salt at the Start/Finish area as well, as we'll have event toilets there... no open fires unless in portable fire-pits, and all ash and other refuse must be taken off the salt and properly disposed of.
