Outdoor Party Games and Music Venue

we went to one of Nikki's friends parties and it was all her friends from that side. It was at this outdoor venue/field area. There was a flat circle trampoline with no nets in the field so a few of us hopped on and we found a ball and made this game where it was a 4-person game where each person controlled/defended a quarter of the trampoline and the objective was either to keep the ball OUT of your quarter or to score by kicking it thru someone else's quarter. We played both ways and it was really fun. Afterwards, Nikki just picked up the guitar or bass and wanted to play a song for everyone. There was this little run down stage that was perfectly comfortable for her for it. There was a lady selling beers and shrooms at this little window next to it so we were all getting something. I tried to buy some shrooms and she wouldn't accept my expired license so I had to show her and email of my new California license pending and she still didn't accept that so I was out of luck.
