Such an incredible place.
How to get there:
Make sure you actually go to the salt flats! Take Exit 4 by Bonneville Salt Flats. You'll pass a Sinclair Truck stop. Keep going and take a right on Bonneville Speedway Road. Follow it till you reach the end. There you can drive on the flats. Be careful if you don't have 4x4 there are unmarked soft spots that are really easy to get suck in.
