I've lit up my pipe in the middle of the day in this big field on campus when there were tons of people all around, but I was sitting by a tree hanging out, and I was careful about it lol. Although one time I lit a joint in my car right as I was driving away from campus, and it was smoking more than I was expecting it to bc it was running a bit, so it filled my car with smoke, and these two dudes walking down the sidewalk saw and were like giving us (my buddy was there too) thumbs up and shit... lol
Never gotten a ticket though... It's really sketch to try anything on campus here, though, since the cops are douchebags here. I've never gotten a ticket, but I know lots of ppl that have.
