I've been backing trailers for over 50 years. Last summer I pulled in to a bluegrass festival and was directed to park in a field, in the first vacant space. There were literally no obstructions. The only requirement being to leave enough space between the other guy and me. Oh, and I wanted to be parallel to him.
It took me about 5 tries to get it the way I wanted it.
I was OK with it.
Until the guy started ribbing me about it. That got me a bit T-ed off. It's not a performance for crying out loud.
