Never EVER do this. Unless you are retarded like me. I get home from a swap meet early in the morning (3:30 am). I open the garage door and stick all the littler stuff of value from off the trailer into the garage so no one snags it. This morning I go outside to finish unloading the big stuff, and my garage door was wide open all night (well, from 3:30-9:30 am). I had 3 alum. intakes, a light bar, a carb plus just everything wide open in the garage. I am very lucky no one took anything.
