Nice wheels! Now, if you can carry a uke on it somehow... maybe some sort of uke hanger, or straps to attach the case on the crossbar.
From the title, I expected a mobile MGM store in a van. You could sell ukes at the beach. It is probably too soon for that, but I could see you kicking back at the beach, playing your uke, and attracting customers.
So glad to hear you are up and about!!!
