I'm actually doing a few more lunch time rides lately. Nice to ride in full sun, although I have to pick my route a bit more carefully. There's a mall (with a cafeteria) and Walmart that attracts old people at lunch time like (insert your favorite simile here) -- and those old folks behind the wheel of their large cars frankly scare me.
Downside is that lunch seems to attract virtual meetings. How come I can never get on anybody's calendar around lunch time, but they're so happy to gum up mine?
Dark never really bothered me after I got my lights down. It just seems kind of silly to go riding in the dark when I'm already home!
