Wow. I'd say you're a hero right up there with the other ladies who did ride the day you didn't. Our bodies can only do so much, and each body comes with its own challenges and limitations. Respect that and be proud of all you've done.
Missouri roads, with the drivers, winds, and hills, can be very discouraging. Some drivers are kind, if you ever need to stop on a rural road people are wonderfully generous, but when we're all forced onto the same road because it has the only bridge for miles or whatever reason, it gets pretty difficult.
