Daves is, as far as I know, the oldest indoor facility in paintball. They've been at the same location for as long as I can remember. One one hand, this is cool because I've seen the area around it evolve. On the other, Daves has no room to grow. So they don't have an airball field, let alone the room for it.
The last time I was there was winter of '07. There was paint pooled on the ground, windows had been shot out, and there were spots on the field I didn't want to run into. Cleanup of the field would take a long time, and they do their best to keep up, but it's obvious that it's not always going to be clean. When I go there, I pack a change of clothing and something to wipe my body off with before I change.
I still like the place! The grunge is part of what makes Daves so great to me. It's a throwback to way back when indoor fields were all like this, and most were worse. The basement field wouldn't be the same if it was brightly lit and didn't have that physical feel to it. I seriously miss the PGP's, even if the new markers aren't a bad replacement. A lot of people get turned off because of the musty smell, but that's indoor paintball. They all smell like that after a while.
The field itself is actually in decent shape. The floor isn't rotting out, the ceilings are in good shape, they replace the bunkers that are worn down. The flooring is the only major problem, and that's going to happen when you have an indoor field. the pro shop is well stocked, and they actually run a good show. The place is a little on the run down side, but for the money you are treated to a good show.
If you're a speedball player, or you're looking for airball style play, don't go to Daves. You'll be disappointed. If you're looking for a scenario style field, or you have friends who never played before, this is a good field for you.
