When you buy your vehicles at the auction, like me, you don't have to worry much about them being stolen.
A friend of mine was attending the Conservative convention in Edmonton, a couple of weeks ago. One of the delegates had his vehicle broken into and cleaned out in the parking lot at the Hotel Mac Donald. No place seems to be secure, but it's important not to leave anything of value, visible from the outside. My friend left a gift wrapped coffe mug in his truck on a previous trip, to find the window broken and the mug gone, when he returned.
I've been keeping my eyes open around Sundre, but your buddies truck is probaly long gone from here.
