SIR is a rock pit! All of my friends who race there complain about it, but at the same time it's the closest track in the area since the one on the other side of Kent was filled in for a housing developement... what a waste. SIR is not a safe place to ride anymore. The manager did NOTHING to improve the track over the winter. They claimed that they were going to regroom it, bring in new ROCK FREE dirt and revamp everything... yeah right! It's the same dirt as last year with the same rocks. The crowds are ok. I was there last week for practice and it was pretty busy from 6-9, but they open it at 3. If you can get there early for practice good deal. If SIR is convenient for you then go for it, but if you have the means to ride elsewhere I STRONGLY recommend that you do. Just my $.02.
