Welcome to the site. Lots of great resources and help here.
I miss Tucson. I lived there for a year about 8 years ago.
And I really miss the racing. I worked for the Robles' when they ran USA Race Track, and did some stuff for Benji at Casa Grande as well as Royal for Law Cruces & El Paso. Good dirt tracks in that area. I also was on Adam Crippens crew and helped him & RC.
