I have the old work horse, a 2004.5 Polaris Sportsman 500. It has ITP 589 M/S tires on it and its pretty hard to stop. I use it for everything.
I also has a 1989 Yamaha golf cart with a 4 inch lift and 22" balloon tires on it. It gets used at camp for the summer and for hunting in the fall because I can carry four guys on it. I built a trailer hitch for it and I have a little trailer I can tow with all the gear. It's white right now, but thinking of putting a camo wrap on it.
