Take care on that bike Bruce. I have seen your road bike, it looks fast and fun. Perhaps augment with a super stable cargo type, less face plant-able bike ?
Lots of examples, for example:

If bikes were Sexauer guitars this is the "Sexauer" version:

The new disc brakes are a revelation. Also there is a different physical relation with the bike leading to more control. You have half a chance with potholes and, with wider tires, many general road obstacles becomes no big deal. These bikes don't go that fast but you already got that covered. Plus they carry stuff and better that the bike is the workhorse than you.
But maybe you weren't looking for advice on how to spend your money...
Be well, keep rolling!
