We've just run across a new website Off-Road Atlas, which is exactly what is says, an off-road atlas to public parks & trails across the country. If you know of public lands or parks open to off-road vehicles, post them up here. If you're a newbie, looking for a place to wheel, type in your zip code and you'll find out what's in your area (or plan a road trip). The site is still new so there's not a ton there yet, but if it becomes what it hopes to become, it will be a useful resource for all wheelin' fans. So add it to your favorites list and let's see if we can turn it into a great site.
By the way, they are running a contest now. Post a location and be entered into a drawing to win $100. The contest runs through mid-March.
