My father-in-law turned 70 this year and is pretty active. This year he even started riding his old Raleigh Sprite to the soccer fields to referee the kids games. The Sprite's pretty well had it (although I'm eyeing it up as a restoration project) so we went out and bought him a new Raleigh Prism for Christmas. The Prism is pretty basic, but has front shocks and a seat post shock.
Everyone got together on Boxing day to exchange gifts and we saved the bike for last. Good thing, because he wouldn't have been around to see much else. About five minutes after everything was cleaned up, his helmet was on and he told us that he was "just going to check the bike out". When he came back, we talked in the driveway for a few minutes, then he started walking the bike up the drive to the garage. As I opened the front door to go in, I looked over my shoulder in time to see he had climbed back on, crossed the grass, hopped the curb and was away again.
He did come back but he hasn't stopped smiling yet!
