I was caught and chased by security when I was 17..booze..blond hair females ID and her student ticket...I used to sneak mine in using my stomach. It was crafty and I only got “caught” once. By “caught”, I mean there was an incident.
The old Army wool blankets, even the newer ones that are 80% wool, are quite warm . . . and instead of "cardboard" to sit on, go the hunting section of your local outfitter and get the foam "turkey" seats, very warm for your tush!! Oh, the suggestion of the hand warmers is golden . . .
Have fun!!!
Go Vols!!
