I used to get asked why I was building a car and sinking X amount of dollars into it, just to load it on a trailer, drive 13hrs and make 10 runs in a weeks time.....I still don't have a good answer......it's Bonneville man!
Some people feel the need to drive across the country to go to Hot August Nights or Sturgis or....whatever.
My friends and I have done four of these events, Pahrump, Laguna, Portland (lame) and Thunderhill. We share the fuel cost, kinda, lodging and the driver pays the entry. Every one of them has been a complete blast, not just the track time but the other folks involved and the time spent with friends.
We'll continue doing the events closeish to home and see what happens next year, I can guarantee we'll be having a blast no matter what cars/classes are running.
