Even with locked doors they get in! My son and I was at a meeting in Dallas one year- he'd won a set of golf clubs!!! Now that is not a small piece of change - and we came out the next morning to find they'd smashed almost every window out of the car - it had to be a lucky hit - and the golf clubs were not to be seen in the car so they did not know when they broke the windows out that there was a thing worth breaking in for. He not only had to pay his deductible for the broken windows, he lost his golf clubs and on top of it because it was his homeowners policy that covered it - his home owners insurance went up the following billing period!!! So, talk about getting hit hard by a bunch of theives; I actually vowed to never return there ever again in my life! it is not worth the risk, and we were in a very nice hotel, and parking ramp etc... who would have thought?
