Make sure the garage door is propped totally open, with a screwdriver stuck in that little hole you drilled in the track specifically FOR that purpose, before trying to drive through said door in your tractor. The tractor's ROPS will fit with about 1/2" clearance if the door actually IS propped completely open; it doesn't fit, otherwise..
Interesting ones about the corn - bears like corn, too. They've been known to tear the siding off the garage to get at it. Quite, ummm, 'invigorating' if they come in to get it while you're in there.
Note: it is impossible to hear a bear walking on concrete while your head is jammed in the wheelwell of an F150. Bears walk VERY quietly.
Don't practice chipping golf balls anywhere near the windows of your garage.
Don't be distracted by the neighbor's shouting match with his wife, and forget you left the full oil drain pan under the car, where it will snag on the front air dam (darn low cars, anymore) when you back out, simultaneously spilling the oil and destroying the drain pan
but not damaging the air dam, amazingly enough.
A vice is a very good accessory to have on a drill press. You CANNOT hold a piece of steel tighter than a vice, nor does the vice have skin, which the steel will tear off your hand when the drillbit grabs and rips the steel from your hand.
Don't forget a well stocked First Aid kit, and a heavy duty Fire Extinguisher (or 2, or 3).
Almost forgot, if you have a truck cap, be sure the cap's rear door is closed when you pull out of the garage, so you don't tear the door off the cap or the handle off the garage door.
