Fort McFCoy is now a closed base only military personnel are allowed on base, especially since sept 11. The entrances have been beefed up and have anti-entry barriers. I have been on a few trails that boarder the base but have never been approached. Many people live adjacent to the base and farm there.

That said Black River State Forest no longer allows free trail runs. I have contacted the Jackson county police, who have jurisdiction there, and they have said per a phone conversation, I have nothin in writting, quote "If a road is marked on a map and is NOT designated as ATV/Moto or snowmobile ONLY, of NO MOTOR VEHICLES, then it is legal to drive on." BUT, and I say but, there is a movement to restrict access to even logging roads, which are not on maps because they are so new and very clearly vehicle roads. The tree nuts would like no vehicles allowed at all to these areas even given the remoteness of the area.

It appears that "Mud" clubs like the site you gave me are responsible for the demise of 4x4 in wisconsin. There was a movement in 2000 to end free 4x4 in public areas that succeeded. The 4x4 that most of the xterra clubs engage in are different than the 4x4 clubs of old. In wisconsin they tended to be rip it up types. They gave 4x4 a bad name AND helped to stamp out ALL 4x4 in WI. I contacted J&L 4x4 of Sun Prairie, WI, all they do is 4x4 mods, and they indicated that if you did not know someone with land in WI you would not be 4wheelin' here. Now, if you have ever been to Sun Prairie, for maybe the Corn Fest, 'nough said, a good majority of the vehicles are modded out 4x4's. Not that EVERYONE in SunPrarie is a red neck, but.

So the answer would be no. these are not the trails I use.

If you would liek more info on the Air Guard bombing range it is named Hardwood. Do a search on MSN for 'hardwood bombing range'. You get an eye full.
Here is the official site for the range, Harwood Bombing Range

But the search again shows why we cannot 4wheel in wisconsin. i.e.

The last one is the most current. Black Hills sounds good but it is a drive from Madison and would need more time to go.

Hopes this helps.
