Since then, I've ridden to that same gate a couple times, including once with granddaughter Mackie. A bike-riding friend, Paul, suggested I take a close look... 50 yards or so before you get to the gate, there's an obscure "nature trail" that continues off the right side of the pavement. (He hadn't traversed the trail, at least on bike, but he had noticed it.)
Last Saturday (4/20), I decided I better check out that "nature trail." And Paul was right.
I took to the trail. There are no signs, indicating "private property" or "no bicycles" or any other such restrictions. I anticipated that I might get hollered at, but I've survived hollerin's-at in the past. (But just in case, I was glad Mackie wasn't along; she doesn't take well to getting hollered at.)
