That was my hubby. We told rider services the night before when I signed up for medical sag that he was going to do that. But in the am, someone who knew better at rider services said "he's going to get pulled over!", & he was-but they let him finish the flat 40 miler. For safety reasons they don't allow solo tandem-ers. Might be sketchy on descents I suppose. Thanks- I am back to the therapy pool exercise while my Achilles settles down again. DH is now intrigued by the Cycle Greater Yellowstone ride, so that may be next year's adventure!
