Wow... despite the ease of accessing a D110, I do not want to move to the UK now.
Approximately 20 miles from my house is an ORV (Off Road Vehicle) Park of about 600 acres. It's was clearly a riverbed sometime in the past, but when the river changed course it dried up. The park itself consists of the old river bed and both banks (probably 100 - 200 feet of elevation change on both sides. With some forested land, artificially piled boulders etc. It is great for saturday entertaining but altogether not very adventurous since you can't really go anywehre except tool around in the park. Usually it's pretty empty on snowy/bad weather days since the atvers and dirtbike crowd down't like the mud as much.
This is looking down on the river bed. Both sides are open to vehicles.
This shows the boundaries... although it's pretty obvious from the tracks.
Additionaly the Federal Gov't is requirng all national parks to publish vehicle use maps detailing EXACTLY where what types of vehicles can be used. Several parks have made maps specifically to emphasize vehicle adventure routes, such as the Gifford Pinchot National Forest near Vancouver, WA. It's a little drive for me, I'm closer to the Colville National Forest or Okanogan National Forest. Here I haven't even addressed other state parks, but there are many.
Information on Gifford Pinchot since I hear it's pretty cool.

Definitely not pants, but some places can definitely be more than a daytrip. Next summer I want to head out to Gifford for a couple of days... I just have to get the wife ready for the idea first.
