Pros,
They go everywhere, we had one in our deer camp in northern MN. We'd hunt all week and leave the deer hanging out in the bush. The last Sunday we'd take the Rokon out and drag them all back in. They'd even ride them over beaver dams.
Cons,
They are slow and aren't street legal so you have to haul them everywhere you want to hunt.
Take a look at a TW-200, street legal and will get you just about any where seeing as almost all public lands now days you are restricted to established roads anyway.
