I heard Hannibal kind of sucks. But that's just what I heard. I have never actually been there. I heard they just opened and really only have a few trails open. I don't believe that there is much natural rock either. RORP is pretty kickass though. The same people own it
Hannibal has only had a few invitation only groups or clubs through and is not open to the public yet as far as I know. All that has gone on there so far is a couple rock crawling comps. There is supposed to be a few miles of trails ready for the grand opening.
