Glacier & Yellowstone Natl. Parks MT

[Northwoods]

We will be camping our way to Glacier and Yellowstone Parks from St. Louis. Does anyone have any experience camping at St.Mary's campground in Glacier or anywhere in Yellowstone? We had a great time at Rocky Mtn. last August in the Morraine. It was our last trip in the old Coleman, our TM arrived 3 weeks later. We plan to do some Lewis &Clark exploring, Oregon Trail and family tree researching. We leave July 26 and plan many stops on the way. We'll go up through South Dakota and back through Nebraska. We'll be towing our 2330TM with our 2000 Suburban. Thanks. Northwoods, Ken and Olga Smith
