Best Bouldering in Tucson?

I'm visiting Tucson and and looking for a place to boulder. Any favorite spots would be stellar. A good rock gym would be cool too.

Look up rocks and ropes for the gym, they have two locations one of which is mainly bouldering and its pretty cool. As far as bouldering goes I'm not a big fan of bouldering so someone else may have much better suggestions than me but personally I have only been in ventana canyon and sabino canyon for that. Ventana has some good bouldering but the brush can get pretty thick in the creek. Sabino canyon has some great bouldering problems but they can be pretty spread out throughout the creek, if you walk up the tram road you'll see what I mean but some problems are pretty cool because the problem goes over part of the pool from the flowing water in the creek. Also, on the phoneline trail around tram stop 9 their are some V hard all over the place you just gotta look for them.
