I'm in this club. I ride solitary every day. If I pass or, more likely, get passed, I try to say Hi, but unless the other rider is a commuter like me, they usually just blow me off. No biggie.

I do rides on nice weekends just for fun. No real planning; I just decide I've got a few hours to kill and go out for a ride. The one thing I'll do on these rides is *avoid* my normal commute route, even though that's the way my bike automatically points itself. I've even done a century with only a couple of days "prep," most of which was trying to figure out what route I'd take. That was also a solitary ride.

Yes, I've biked to my doctor. The first couple of times they remarked, but now I think they pretty much expect it.

I just got through a round of physical therapy. Most of the appointments I managed to get for right after work, so I showed up in full winter kit and only took off as much as necessary to get the exercises done. It was a shoulder injury, so I was riding the hand bike, doing the rubber band things, etc. wearing my base layer, rain pants, and shoe covers. They let me bring the bike inside and park it in the exam room during my sessions.

Oh, and the best part is when the weather is nasty here and the other guys come dragging in because they knew I'd make it and they couldn't let themselves be shown up by the guy who rides the bicycle to work! I just smile.
