I have friends who fish down south (MO, AR, FL, etc) and they have an assortment of prop locks, drawbar locks, trailer wheel locks, actually, they have a lock for just about everything that is lockable. I always said to them, and with no small degree of pride, that we don't need that stuff, 'cause guys don't do that up here. Well, evidently I was wrong. Hopefully this is an isolated incident and we can all get back to worrying about where the walleyes are biting instead of worrying if our trailer is going to be on blocks when we return to the landing.

One additional thought here. If you do see some guy removing trailer guides or a spare tire from his trailer, be aware that the trailer he's working on might not be his. Don't confront him, but a good description, or a photo, or a license plate number can do wonders.
