Seeing as he is past seventy years old, we thought it in Uncle Chuck's (and our) best interest that he not actually try to ride the unicycle. He did however give us some pointers on how the feat might be accomplished. Raising the seat was not too difficult and with something steady to hold onto one can even keep the thing upright..
His other suggestion? Toss a rope over a beam in the top of the barn or a garage and use that to keep from landing on your head (or butt) while learning to find your balance. I think a tree limb would also work out rather well. Uncle Chuck did feel it necessary to sit on the unicycle and show the guys how to get started. I think he wished he could still trust his body to take off riding circles while the rest of us looked on in amazement.
We all know that somewhere out there is another family member just waiting to find his or her place atop this marvelous contraption. Maybe its Steven... or Hannah!
