This just in from Sgt. Dave Reagan of the Sheriff's Department - some good reminders in here for all of us:

Property crimes investigators report that the annual summertime crush of vehicle prowling incidents has begun and that losses are mounting.
Thieves know that boaters, hikers and walkers/runners don’t want to carry wallets, purses, cameras, GPS units, I-pods, I-pads and I-other things while they are out enjoying the day.  They consider parking lots target-rich environments for stealing items easy to pawn.The best way to defeat a vehicle prowler? Keep your valuables out of sight, preferably placed in your trunk before you arrive at the county park, Centennial Trail or boat launch parking lot. 
Criminals frequently sit nearby and watch for would-be victims who stuff their valuables beneath a seat as they lock up their vehicle, and it takes mere seconds to break a window to gain entry.

Another safety tip is to place your vehicle registration somewhere in the car where it would be available if needed, but not easy to find by a thief. 
A suspect who sees you start a day of fishing, hiking or soccer can reasonably assume that he has time to get your home address from the registration and pilfer your residence before you return.
Thieves typically break into vehicles where they see something to steal, rather than breaking into them to look for something to steal.Taking a minute to conceal your valuables may mean the difference between being a happy camper or an unhappy crime victim.
