As an aircraft mechanic for over 20 years, I've gotten used to doing many a walk around w/ the crew. I always look in a circle where ever I walk, I touch all doors and latches to ensure they ar enclosed, I point my finger at stuff I can't touch (running light check), and at the hitch, I touch everything in a clockwise pattern to ensure all is connected and nothing is hanging down.
The funny thing is, I remember my dad doing the same thing when we were camping 30 yrs ago....guess the apple doesn't fall far....
