Good report!
I also tour alone. It seems my generation is the worst for group activities as we are so used to doing what we want on our timetable. Make a plan and sure enough someone will not prepare, not show up, or want to change it.
I don't care what the plan is but once I've invested myself in it I want to try and see it through.
If do group stuff I really let go of any expectations and just enjoy the company. I did that with my son and brother and, while we didn't cover many miles we had fun.
It would drive me nuts though to want to do a certain route and not be able to because of other people not prepping for it or not caring if it were actually done.
