Hi Ron,
It would be great to have you on the ride, but I understand about spending time with your Dad. You could climb with us for awhile, anyway, even if you didn't have time to do the whole ride.
I think Jackie and maybe Maria are only going part way too, so maybe you could ride with them. They're both good riders and fun to talk with as you ride along!
Best Regs,
