Been a 'local' for most of my life to the Gilbert OHV park. Currently im about 10 miles away.
Its a nice area. Interesting because the whole place is actually an old steel mine dump. Most of the rocks are blast rocks. Its very cool. That being said, I wheel their MAYBE twice a year... (Look up Mesabi Mountain ORV Trail on mn-jeep.com to see what my club has been doing for the last 2-3 years)
For a meet and greet it would be a nice area due to be able to travel from the park to a campground by a direct route. The campground is on a 'lake' called "Ore-Be-Gone" because its an old mine pit that is over 400 feet deep. Its actually the mine that the material thats currently the IROHVRA (Iron Range Off Highway Vehicle Rec Area).
I have done lots of work in the interior of the park from trail maintence to new trail construction. I would think that you could wheel for a solid day in the park with a stockish Jeep. Lots of ******** stuff too..
