Not necessarily trouble with break-ins, but there have been even more people than I'm used to seeing hanging out at the launches for non-recreational purposes (mostly drug use, judging by the junker cars they're usually sitting in and their suspicious behavior. They're probably just there to get high, but with drug addicts parked near your empty rig, you're always at risk of the ol' smash and grab. Now that the season is more or less underway and the launches will be more crowded with people fishing (and occasionally enforcement), they'll probably start looking for new places to hang out.

Like Rivrguy said, there's always the usual drinking, building fires, doing donuts, and general loitering going on, especially in the summer. Not much has changed, but it seems more and more common.
