I did one of these in college back in '05 or so. Except it wasn't 24 hours, and there was no lottery. I was up late studying when a suite mate came into my room and asked, "Do you want free Chick Fil A for a year?", so 4 or 5 of us hopped in a car and drove to a grand opening. The experience was fun and really memorable! It was cold, and they had set up a bunch of portable heaters. At one point before the official opening, they passed out free chicken biscuits. It really ended up just being a fun tailgating experience, and we got a bunch of free food coupons as a bonus. Again though, it was only a few hours. I don't know if I could do it for 24 hours, even if I were 20 again lol
