Pulling the rotor button was my go-to...before I updated to HEI
Personally, what would worry me more is someone pulling up with a flatbed trailer and a winch. That would be a super easy way to steal a stovebolt. A GPS tracker, parking in well-lit lots with cameras close to the front desk, and a quick dis-able of the ignition system sounds like a good combo to me.
Could you rig up a second ignition switch in a hidden place, that when switched off would disable cranking?
