Naked Jogger Guy.
Saw him from the back side (fortunately) on a fairly long and secluded section of the local canal path. He didn't hear us ride up from behind and I nearly scared him out of his running shoes when I hollered a warning to pass. Turns out he's a regular at this and has figured out what time we ride through and has adjusted his time back just enough to miss us. To bad he doesn't know we have a lot of extra time built into our ride. I think we may push our start time back maybe twenty minutes one day this week just to mess with him.
