Dolores Park isn't particularly known for its drug-free baked goods, which makes the fact that some DP neighbors are slanging their child-friendly treats like crack just that much richer.  Just go up to the string, attach a dollar, and pull the string.  Up goes your dollar, down goes a cookie.  And this being the city that eats the internet for breakfast, loves it.
