I had a boot on the wheel, a pin lock and a hitch lock. They stole the trailer and my two sleds from the back of a house in a busy neighbourhood where I was storing my stuff. I found out about it when I got a bylaw ticket for parking in an emergency lane. They took my trailer and parked it behind a body shop and I got a ticket mailed to me. A tracker on the trailer at least gets you to the guy that knows where the rest of your toys are. I can tell you from experience, its the best way to catch any of these guys. They don't care about making noise, being seen... nothing. And they don't care about stickers. It take them about 3 minutes to call BS on a sticker......They know that even when they are caught, a couple days in Remand and a Judge will always let them out on bail......and usually its a no cash bail. Go with leg hold traps and tiger pits
