If you're out East, there is the Mason-Dixon 20-20 http://www.masondixon20-20.org/
Also out East is the Void Rally http://rallythevoid.org/
If you're in the Midwest, there is the Minnesota 1000 http://www.teamstrange.com/
If you've done a certificate ride and not a rally, I'd strongly suggest starting out with a 24 hour rally. Some people find out they don't like bonus hunting and the record-keeping aspects of riding in a rally. If it turns out you don't like rallying, it's better if the time and money commitment is 1 day instead of 6 or 11 days. I've had a couple of Butt Lite riders tell me at the end of 6 days that they learned they didn't like rallying. Not sure if they felt the same way going in.
