On a more mundane note, we have had our third rear flat tire on our DaVinci Grand Junction in 3 weeks. I guess more people out walking since Covid 19 is leading to more broken glass on the road. I am glad we hung onto our Trek T900. So, on those mornings when we wake up to find a flat tire, I can grab the backup tandem and wait until the weekend to change the tube. Having a backup tandem has its benefits.
