I have just acquired a 2005 Arctic Cat 650 Twin 4x4 ATV. Its got brand new rims and ITP MudLite tires, Winch, Brushguard, Front Locker, Rack Bag. I think that ATV's like this are probably the very best vehicle in which to get just about anywhere. The draw backs to these are
1. No protection from the elements
2. Gear and supplies are limited
However if your goal is to get back and away from people the very farthest you possibly can and you can pack light then these are a ton of fun and remarkably agile and capable machines if you are a skilled rider. I have 4-wheeled just about every vehicle possible and I find ATV's to be my favorite. Getting stuck is usually and easy recovery, breakage is minimal, the light weight helps, the open air feeling has a coolness factor.
