The guy should've had a Dinotte on his mobile meth lab, to make it "Legal". That's my conclusion.
I was not aware that trailers (bike trailers) needed lights of their own. I would've figured the bikes tail light would be enough, so long as it's not blocked from view by the trailer.
Anyway, I would have expected someone to get busted for having pot plants growing in a plexiglass enclosed velomobile, in their backyard, but not this. A velomobile can be used as a "cold frame", or a miniature greenhouse, to get plants started early in the season. I don't know anything about methamphetamine.
