You folks probably don't care, but just wanted to say this. I am 42 years old coming up on Monday and I can count on 1 hand how many times I've ever seen someone riding a bike out in public that wasn't a kid in a neighborhood or on a bike trail.
I'm not a commuter, but I do read this forum for any pointers that may pertain to my riding (like "where to stop at a red light" just in case I ever find myself in town with my bike.) I was driving home from town (about 30 miles, hence, I don't commute because I don't have that kind of time) when I made a turn and a 14 year old kid was riding down the middle of the road on his bike. He didn't ever signal, but he was riding right in the traffic lane (not a lot of traffic) and followed a few turns while I hung out a ways behind him. Eventually, he took the straight/left turn lane heading down the hill and turned into a gas station. Have to say, it was pretty cool seeing him.
I did feel a bit sorry for him, though it is his own doing and probably just being a kid as this wouldn't bother someone of that age, but it was 40° and pouring down rain and there he was on his bike in a t-shirt and pair of shorts, rooster tail flying off the back tire, motoring through town in the lanes. Had he looked back at me (his head was on a pretty good swivel looking all around and he rode most of it standing up looking around) I would have given him a thumbs up.
Like I said, I can count the number of people on bikes on the roads other than kids in neighborhoods on 1 hand in all of my 42 years. This kid makes number 5. I thought it was real cool seeing him. He is the first of the 5 that I have seen actually riding in the lanes rather than off on the side.
