I'd be happy to spread some at the
Denver Skate Park. If it helps in your desire for variety in location, I could also keep some until next time I'm up in the mountains, then spread them at the summit of, say,
Loveland Pass (el. 11,990 ft/3,655 m) on the Continental Divide, where the snow never melts. I'd be happy to vandalize either place with a sticker too.
The Embarcadero (& nearby Wharf) in San Francisco is awesome. Definitely among my favorite places to visit in the bay area.
