PM me, and I'll tell you everything I am experiencing as a first year racer.
If you are from Keswick, you are in luck. The CSRA president Ken Avann lives there. If you email the site, they will give you info or you can call the office as well, their number is on the site too.
CSRAAs for tech requirements on your sled, it is all on the site. You need to have a proper snow flap, kill switch, etc, but your 440 probably already has all that. Safety gear is available on site at the CSRA trailer.
On my SnowGoer blog you can see what has been taking place so far this year.
