My buddy had his skis stolen at a nice motel in SLC this winter. They were sophisticated enough to just go through the back window of his CRV, so as to not set the alarm off. There were valuables in the front seat area untouched.
I was just up in Killington a few weeks ago, and my friend there told me to hide all valuables in my car as I parked in his condo lot. There had been incidents, he told me. While I was waiting for him, I watched a junkie stumble out to the parking lot from another building. I have good junkie radar from living in 70s NYC. I always lock my skis at base areas in Vermont for the last decade or so, when the drug problem really got out of hand up there.
