Myre-Big Island State Park, MN

This would be our second stop on Aug. 28 for one night only and then northward to a FamCamp at Deparcq Woods, Ft. Riley. Then on to Bemidji Lake for 3 nights. Forgot it was Labor Day weekend and wanted to stay to Itasca SP, but acted too late it was full. So we'll stay at Bemidji, tour Itasca and else where before moving on to Cascade River SP and on to a Phoenix Cruiser Rally outside of Duluth. Then work our way home to St. Louis.
More than open to any hints, suggestions or recommendations for eateries, sights, history or whatever!

thanks
