I went riding with my wife tonight and around dusk we came across a hiker on the west loop carrying a roll of orange material. It didn't strike me until we were further down that she had been marking branches and trees along the trail with this orange plastic sort of tape she was carrying. I thought to go back and ask her about it, but I figured I'd have no idea what to say, and that she probably would have thought that what she was doing had some purpose to it and I didn't want to chance souring my first ride in a couple weeks with an argument, plus with it getting dark quickly I didn't want to stress my wife out about it, either. Is this sort of thing as unusual as it seemed, or was it someone just up to some regular trail maintenance activity?
Also, the past couple of times I've ridden there I've seen a bunch of empty plastic bottles; I fully intend to bring a garbage bag next time I go.
And, I've noticed a strong, sweet, almost perfume-like smell while riding the east loop. Does anyone know if it's from a plant native to the area, or is something else causing it?
