Nope, that little grey Subaru isn’t racing around on a snow packed parking lot. Last time I was out at the Bonneville Salt Flats it was a grey day, but I still had fun.
Watching the cars racing around out there. It wasn’t during the official races at the flats, but I’d bet most weekends you can find someone out there just pushing their car to it’s limits.
Of course you have to take into account that the underside of your car is going to be crusted with salt when you’re done. Salt and cars don’t mix too well, gotta make sure you thoroughly clean the underside afterwards.
