Today Srivishnu, Clark, and I (Mario) went to Gunderson High School in San Jose to train with some people I met at an SFPK monthly in San Jose. Gunderson High School looks like a jail. Despite it's fugly exterior, it is quite amazing for parkour training. It has extremely grippy walls littered around campus, as well as nicely integrated rails and stairs. I noticed my wall moves (runs, vaults, climb-ups, cats, etc) improve dramatically. 9/10, would highly recommend if you can past the used condoms and 4Lokos scattered in the bushes.
