Wallenberg High School is another classic SF street skating spot. The first thing you'll notice is the giant 4-set, made famous by Mark Gonzales in the classic Blind Video Days video. The 4-set is so big, each one can be skated as an individual ledge. On the other side of the school, there are benches, tables, and ledges. Since this is a school, it's obvious best to come on weekends or after hours. The school seems pretty tolerant of skaters hanging out when there are no school events going on, as long as no one leaves a mess.
