I will be up at the Pipeline Memorial Day weekend also. I have been up there a couple of times. Twice with my TJ and last Memorial Day with my JK. The group I go with are a very good group of people. Very newby friendly and helpful.
Here are links from last year: WI4x4.com • Login
And the year before: WI4x4.com • Login
Check it out. It should be a good time again this year. I go up with my wife, son and his friend. We stay at a hotel in Crivitz, while most of the group camp in the yard of one of the people who live up there.
