This isn’t Calgary-related, but it concerns a really positive aspect of skateboarding.
Jesse Martinez is a Venice Beach, CA skate legend (DogTown/Z-Flex/SMA/World Industries/Blind/Z-Cult/etc). He’s the godfather of the Venice Surf & Skateboard Association (it took them 15-years to get their park).
Jesse spends most of his day and night there cleaning, policing and riding. This is a great example of stewardship– skaters taking care of their own space.
