Comments: available for free from the nearby ranger station. note that for the gill problem v6/v7 you ARE allowed the obvious right hand crimp. it's more like v8/v9 without it. see john gill's page here for further details: www128.pair.com/r3d4k7/HomePage3.html
Comments: Hey - was wondering if anyone had information about outdoor bouldering in the state of Mexico City and nearby. Have tried escalando.net, which seems to have a fair bit of info - but have been frustrated trying to locate (the relatively few) boulders mentioned on that website. Any tips as to useful websites or email addresses much appreciated!
