If you're heading to Resolfen on Thursday night, and can't get into the Abercregan carpark till 5am, go up to Glyncorrwg MTB centre, and they're having a bit of a rally bash the night before. Good food, and beer, and only a 2min drive from the carpark queue. About 15min walk if you don't want to lose your place. (better access to good viewing if you ask the locals too)
