This is a pretty good area. Back when I lived near there, I would climb here quite a bit. There's a lot of routes that are close together. It's pretty popular with the after work crowd as it has light well into the night. Also, more people there during the winter than the summer.

The routes are mostly sport, but there are a few cracks. Natural protection could be tough, but the bolted routes are pretty close by and you can usually clip the bolts. Lots of easy TR access too. There's also an area with cool bouldering. Something for everyone!!!

Lots of new routes going up. There used to be a really good yellow overhanging route...not sure what it's status is though???

The bouldering area has just been expanded - they added a small vertical wall where the rope ladder used to be and increased the severe overhang in the back corner.
