http://www.saltflats.com/We race the bonnevile salt flats here too , the speeds they get up to is amazing.
Do you have a 14,110 foot mountain there that you race up to the top too?
Every year they race to the top of Pikes Peak and in some areas they will reach speeds of 130mph+ and all with a 10,000 foot drop off in some areas, no guard rails to keep the cars on the road :
