We had The Creek in San Bruno. It was part of the "Indian Burial Grounds". I dont think any remains were ever found there. Acres of unimproved land, it was GREAT! Dirt clod fights, rope swings, where I sustained a concussion.
It was part of the city park, they had a section of it that was big BBQ section, where the 'hippies' would hold mini concerts, love ins, we used to spy on them. If my parents had found out the things we saw there!
Way cool, Indian burial grounds. I feel gyped. Our tree fort was hit by lightening in The Field once. We were bummed for a while, then, we rebuilt it from more boards we found.
