Except for my buddy in Fredrickburg VA, I never see any Valks at all.
My affluent neighbor got one of these Can Am Ryker trikes (to go with his Tesla and 30 ft power cruiser boat), but he only takes it out a few times a year (just like the boat). In his defense, both he and his wife work long hours.

I'd love to take it for a spin some time, but would never ask. (And no, he can't ride one of my Valks.)
