That was a big fat fail

I think the idea of locking the cars and posting signs is the most cost effective option.

Electric fences and heat seeking robotic killer beez or fembots are also options but not cost effective since we are talking about 3 acres here.

I was out looking today and only see one set of foreign footprints so I think it could even be a single person. Someone wears a dickies brand size 12 that i have not seen before.
