X marks the spot:
My parking spot. In my garage:
Granted, I can park without this indicator but it's just so much quicker this way. I line up the steering wheel up to the mark on the wall and put her in "P" and I'm done.
Without the mark, I just inch my way closer and closer to the spare propane tank until I get too nervous to get any closer. I could move the propane tank but that would be too logical.
Do you guys have some sort of visual indicator as well?
