Today, I was thinking about this thread while I rode a very popular local limestone loop trail in a forest preserve. As I came upon a group of two families strung out all along the trail, one of them turned and saw me (well before I was close enough to call out and pass), "BIKE, BIKE" and all the kids scattered and ran pell mell into the woods, arms akimbo! I thought I'd fall off my bike it was so funny. It felt like I was t-rex or something!
