This was a good season for me - not yet over, but slowing down - and not because of temps. but because of fewer organized club rides. It's like the skiers who hang up their boards once March rolls around - bike riders here seem to lose some interest once the leaves turn.
I have ridden just under 1100 miles since the end of April - mostly on the '85 Trek that I rebuilt last spring and usually with the club on Wednesdays and Sundays. I like that Trek more than any other bike I have owned except maybe a mid-80's Peugeot I had (and maybe that is just nostalgic thinking). I used to ride solo, but enjoy the social aspect of club riding. Group riding is a bit more hazardous in terms of potential collisions with other riders, but I do think a group is more visible to approaching cars than a solo rider - it's a trade-off I'm willing to make.
Any decent day above 40* is a potential ride day from now until next spring.
