Great tips KC, awesome ignition btw.
River, they make motion sensor alarms for bicycles. I got a chinese one on ebay for $6, it goes off loud as **** if the bike moves at all, and you have to punch in a code to disarm. They also make alarmed locks. Do a Google search for "bicycle alarm locks", there's a ton. That would help dissuade any would be thief. Especially when your bike starts screaming at 120db!
I wouldn't take your gas can with you either. No matter how tight you seal it, it'll still stink like gas.
