It's not the 70's anymore, when us kids rode our Stingrays down to the five & dime store to get Pop Rocks. Oh, those were the days!
I no longer bicycle on public roads if I can avoid it, too many close calls, with drivers just not paying attention. In the area of IL I live, it's harvest season, a lot of the roads are full of combines, tractors, 18 wheelers right now, many of these take up the entire width of the road. I'll go to trouble of loading my bikes in the car and driving to a proper bike path, for safety's sake. It's worth it, the cardio of bicycling is hard to equal in a gym, especially if I'm out for several hours.
Very soon, I'll be moving to a much less traveled area that is all 30mph residential streets with no through traffic, may try bicycling again there.
