Re: Know what sucks?
Assuming your right, take a ride in your other vehicle and look around in areas close to you. My neighbors truck was stolen about a week ago. The theives went through 6 other cars before they found one with keys in the glove box. That was my neighbors truck. They found the truck at an apartment complex down the road. Nothing was taken out of the other vehicles, gps's, radars,etc. Nothing was touched. Kids were the likely culprit.
My point is, it was probably kids walking around your neighborhood that tripped across the keys. They probably just took it for a joy ride and dumped it somewhere. I would search around locally to you and see what you can find. Sorry for your troubles man.
Also, post it on craigslist as being stolen and offer small reward.
