It's a tradition that I didn't know about... at least one summer night a year the air conditioning has to be out at JNO.
Since I like it hot, and I think sweating is good clean fun, I thought it was great. I got enough warning on it to get some gatorade, but not enough warning to wear shorts and a light shirt. So I sweated and danced slowly, and got plenty to drink. I didn't even think it was really that hot.
People were leaving left and right, and center calling it too hot. Maybe 40 people stayed, the hardcore dancers :-) it was fun.
Nothing else was interesting, although in a rare feat I pulled a Maegmariel and snuck out without saying goodbye to anyone.
