It was about five years ago that I had finished mounting side cases and added some extra lights to them. Quick-connectors for those lights were on order, but I was eager to get in a road trip, and so I used some heavier cabling - in the mean time. OK, they DID sorta look like battery cables, I guess.
A lady at the 1st fuel stop was simply gushing over my "green" motorcycle and the two HUGE batteries. She seemed especially happy that not only was it "green" but that it was also painted green.
I said "thank-you" and headed on down the road
