I sometimes think that we give the impression that all we do is goof around, chase after birds and ride our bikes. We do do a lot of cycling, but there's a purpose to our fun.
Robb is going through a phase where walking is more difficult than it has been in a while.
We believe that he is experiencing increased neural activity (in other words, his damaged nerves are continuing to heal), but this leads to inappropriate neural responses, such as discomfort and spasticity and muscle clenching.
It is the weirdest thing. Robb can (and does) cycle twenty miles at a time, but at the moment walking a couple of blocks is terribly difficult.
Okay then, walking is on the back burner, because other activities like swimming and cycling are not only easier, but more beneficial. When Robb rides the trike or swims, he actually experiences a decrease in spasticity (which currently increases when he walks).
With this in mind, we took the bikes out to China Camp in Marin County, because both of us are getting a bit sick of the Bay Trail, and because I wanted to look for spring wildflowers. The trail we rode was quite challenging, and Robb assured me that "challenging" wasn't merely a polite way of saying "this whole experience sucks." There were a lot of hills, and the trail surface was often very rough. The trail was also very narrow, curvy and full of other cyclists and hikers.
I did a pretty good job of avoiding rocks and tree roots, muddy puddles and ruts. But this task was much more challenging for Robb. On a normal bike, you just point your front tire at the stuff you don't want to hit, and you keep pedaling. Riding a trike is more complex. You can see your front tire, but you have to use your brain to avoid running into obstacles with the two rear tires. Robb really had to concentrate as he rode. He said that it was like doing calculus or geometry equations while he rode.
I, of course, kept hopping off my bike to check out the trail-side nature.
The trail-side nature checked out Robb, as well.
(Look over Robb's left shoulder. With the exception of the crazy moocher-deer at Yosemite, I don't think I've ever been so close to a deer.)
Robb and I are both really tired after our day of cycling, but it is a good feeling to wear ourselves out, doing something physical.
