My kids and I are doing the Hiking Club. So far it's been great. We did the trail at Father Hennepin State Park yesterday and ran into two groups doing the same thing (one was going the "wrong" direction and asked us if they'd missed the password). I've checked some of the nearby states and haven't seen anything for Wisconsin, but North Dakota has something called an Adventure Challenge and also a 12 months, 12 hikes program. I'm in North Dakota fairly often for work, but not once a month.
