Break-ins have definitely been a problem there in past years. They even broke into customer cars parked at the house just east of the river, where an outfitter has customers park their cars and the owner watches them. Last I heard, local law enforcement had suspicions of who was responsible, but I never heard if they caught the punks. I doubt it. However, they may have grown up or moved by now.
Caution is advised. Don't leave anything of value in your car. Take it with you on the river instead.
