Our development near Zimmerman encircles a slough/swamp/pond (depending on recent rain amounts), and I would say about 1/3 of the people here have one of these (2 of which are electric). Every night 2 or 3 of them can be seen running around The Loop, as my wife and I refer to it, but I doubt any of them ever take them outside of The Loop, as I'm pretty sure there's alcohol involved.
And the Federales are kinda funny about that...
But recall that this is the same neighborhood where the kids have free reign of The Loop to use for their minibikes and go-carts, as traffic is all but non-existent 99.9% of the time, so as long as the neighbors keep it down, and are sensible about the alcohol (designated drivers?), I'm ok with it.
