I don’t know what to say …
except this guy looks like he is having a lot of fun!
Ha ha that would have looked cool if they filmed it behind a wall so all you saw was rider and horse sailing past.
Fair play to the guy though as he didn’t look all that young.
Who’s the oldest person you have ever seen on a unicycle?
Could be fun to see some really old folk riding. 
Oldest person you’ve ever seen riding?
Me.
Then again, I don’t “see” myself while riding.
