Hey, if you know where East HS is, the roof is an awesome place to train at. The surface is rocks, there are many things to jump over and off of, and walls to run and climb, but ya just gotta watch out for the ledges on the far side, there's about a 20ft drop to another roof. Cant do it now though, since school is out, but I'm cool with the music teacher, and that's how you'd get up to the 3rd floor roof. hit me up if you ever want to check it out!
Later!
