I recently met 3 friends at SMP, they are all new to the game. It was only the second tee box where officer Short McPudgy saw us, pulled his car over, got out, walked through a swamp, told us forcefully that he needed to search our bags.
There was no asking to search, he simply told us "I need to search your bags please." I quickly asked "Why?" and he informed me it was to check to see if we had alcohol. My friend quickly freaked out and opened his bag up. (We were all clean, as I had told my friends to leave their beers at home prior to playing.) Anyway, after he search my friends bag, he looked at me and said "I need to search your bag." And I said "No." That made him mad. He quickly started spouting off that if we got caught with alcohol it would be a $70 fine. I assured him that I didn't have beer, that I had played the course before, and I knew my rights. It was only after I brought it up, that he said that the search was only by consent. I realize that you have to know your rights before you're entitled to them, but still.
I hope his attitude was a result of something else in his life going horribly wrong, not just some pre-determined disposition against disc golfers.
