Great place for bouldering, but didn't have the opportunity to top-rope. If I recall correctly, they only allow for gris-gris belaying, and after I explained that I've been climbing for a decade with my other ATC device the instructor looked at me as if I were insane for still using one. Additionally they wouldn't allow for me to get certified on the gris-gris to belay my partner with no experience, albeit the technique is nearly the same. Oh well, I do understand it's for safety, but definitely hampered my day. Seemed like a fun place, would like to go back again if I didn't live conveniently close to other gyms in Portland.
