It takes alot of time, money, and good help. Good fresh clay every other year. The RIGHT equipment, some ingredients, and knowlege. I was part of a great team that did Thunder Mountain surface from 1992-2005. We had this great Blue Clay pit 1/4 mile from the track and we put 300 loads of clay on the track every other year. The weather dictates when you tear it up EVERYWEEK. We would tear it up Friday night, work our magic, lay it back down, water it till dark so when we started on it again Saturday morning it wouldn't be dry. I was asked by Gary Roberts if I could help out Ronnie and Jamie at The AFTON SPEEDWAY. I gave Ronnie some of my secrets and it seems to be a big hit over there. To bad Afton is so far away from my house because I would love to help out them out more. The blue clay they put down looks excactly like the stuff we put on Thunder Mountain every other year. I have some vacation time coming up and I hope to get over to Afton to help them some more. G
