Sounds very doable with the camper. I will be leaving Milwaukee around noon to 1. I beleive it is a 4-1/2 hour drive to Goodman. I think I could get there around 5 to 7, 7 being the latest. To make things easier on all of us. If you can give me directions or (Lat and Long) from Goodman. I should be able to find the trailhead leading to the campsite. Then I can radio you on FRS channel 10.
