I am looking into going to Wyoming in early to mid June of next year, after planting season is done. I am in NW OH, and am looking for some good sites between here and possibly Yellowstone. I have a 35' Sportsman 5th wheel, behind an '05 GMC CC. SB. Duramax. My daughters will be 7 and 11 months by then so there needs to be stuff for them as well. I am not dead set on a route yet either, whether it be down 80, or a scenic trip across 90. I am looking at possibly leaving on a Thursday evening, so we can get well past Chicago the first evening, and returning home the following Sunday/Monday night.( 11-12 day trip) Any suggestions would be greatly appreciated. Thanks
