SoMa; Folsom at 2nd and half a block away, Hawthorne st.
Want a free tour of my neighborhood?
Folsom X 2nd, Millenium sq, some mild to moderate jumps and strides at various heights, good walls to leap over, inside there is 24hr fitness which has a nice rail to jump on.
Folsom x 2nd, across the street, a few angled brick "obstacles" to cat leap to (the angle is a challenge).
On Folsom and Hawthorne st is a nice wall of varying height; great for practicing kongs and, as a bonus, there is a stop sign a few feet from the wall. Jump to the stop sign from the wall, land feet just before hands, like a cat, except with the pole, I like to use arch of foot, not ball of foot (though I'm just a beginner so take that advice with a grain of salt).
On Folsom closer to 3rd, a nice flat-topped railing to practice rail walking (easier).
On 3rd between howard and Folsom, nice wall by a place that's apparently banned (shhh!)
On 3rd, between howard and mission, a nice structure for a couple of cat leaps (you might get kicked out, careful) and another nice wall to kong.
Found another wall but quite figure out what to do with it.
Lots of stuff in a close vicinity; always another spot nearby, should you be asked to vacate private property.
