Daytime, on Rail-to-Trail? I wouldn't even have my lights on.
yeah, it's funny. I was on a trail a week or so ago & I saw someone in yellow w/ a bike light, nothing obnoxious, but I thought "well that's not necessary". but I have been on crowded trails w/ lots of pedestrians & when I'm scanning the trail in front of me, planning my passing, I don't mind knowing that one of the objects ahead is actually a bike coming toward me. it helps me plan my line
