FWIK those are illegal on asphalt and must be carried around on trailers. unless you're REALLY getting into that, you could try leasing/renting or whats it called.. check it out. had some palls once that were nuts about it. as for me, i only tried it in florida, which gave me a license lol.
maybe you have the space/land to mess around with such 'manned' carts ? its by far more expensive than rc (!) well compared to 'Pure' on pc <atv game> i guess so!
perhaps we need a 'cart' forum kategory for that heheh. if you pick the way pics are welcomed anyways.
there's some cheap 2-wheeled offroaders here, they aren't even expensive, but loads of fun. in contrast to motorcycles and stuff they are ultra cheap. doesnt spend much gasoline, loved them! also had a pocket bike once, wicked, hilarious when the dudes got drunk, imagine folks of 6'4 with that tiny thing. ill try look for a pic, it was pretty neat and just as it doesnt fit in a pocket, it was far from 1-size
now theres some truth that big boys need big toys LOL. Wonder if they grade carts in scales too.
