Strangest thing found on my commute is probably Gas Monkey Garage from Discovery Channel's Fast N' Loud.
I'd never seen the show, but flipping around the TV a few weeks ago, they were showing a shot of the Dallas skyline. I thought, "What is Discovery doing in Dallas?"
So, I watched a bit of the show and when they showed the garage logo, I knew I had seen it somewhere, but couldn't place it. A little googling and found out I have been riding past their garage for years. Their old location, only occasionally but their new spot is on my regular route. I did see Aaron (the bearded dude) going out to leave for the day, one evening, as I rode by.
