I'm still riding, but on a recumbent now. The ride rhythm on a 'bent is so different than an upright road bike (fast on flats, slow on hills), I don't ride with a group anymore. Like Bostic, 99% of my rides are solo.
The other things that's changed is that I'm getting so much slower as I age. Just don't have the power I used to. Oh well, getting older is better than the alternative
