Great news Retro! Some of my good cycling friends have had cycling accidents and it's interesting how their reactions have varied. I'm sure it's been a real challenge for you but it's great to hear you're over the top of the climb.
I've got to put the Katy Trail on my list of To Do's. Plus it will give me a good excuse to get a gravel bike that can handle panniers.
