I've talked about the "Swim Mobile" in the past, growing up semi rural I had no idea such thing existed, I was even more surprised to see what other roving entertainment centers were available to those in the inner city.
The teen canteen provided entertainment, hot dogs, soft drinks and a possible place to score pot from a friendly musician!
Aw yeah, it's time for neighbours to let out their frustrations on each other with the roving "Boxing Mobile". They should totally bring this back, I'd go all MMA on my neighbour Doug for his noisy ass mower.
It's a big truck full of Roller Skates and they just hand them out to any kid! Imagine the sadness you'd feel as you see the Skate Mobile pull away while you're tending to your numerous cuts and scraps.
It's a roving playground complete with slides, a functional basketball net and swings. I'd feel weird living in a place where the park drove away at night...
Finally there's the most logical and functional of them all. Not as flashy as the others but my goodness, an idea that will never go out of style..
