When my 2 grandson's were ages 7 and 5 respectively, I was finally "allowed" to take them on a month long RV trip to my home state of Michigan. I had always taken a months leave every summer and headed north to Michigan with my own girls.. now it was exciting to share all my Michigan memories with my grandsons. We loaded up the 22' travel trailer and full size conversion van with 7 dogs, 4 parrots, 1 cat and 2 grandsons. Our first stop was "home" to Port Huron to visit family, then up to Lakeport State Park for a few days enjoying the beach & campground, then to Croswell to experience the "Swinging Bridge", then on up to Gaylord to "Call of the Wild", then Mackinac City touring the fort before crossing Mackinac Bridge to St Ignace. We always stay at Castle Rock Camppark, (my favorite campground). Super folks, beautiful campground, beach, playground and wonderful base location for all Mackinac has to offer. We stayed at Castle Rock Camppark for 2 weeks (never long enough!) visiting Mackinac Island, the Soo, climbing Castle Rock, visiting the Indian Village, Mystery Spot, then it was time to head south again, stopping in Port Huron again this time at the Port Huron KOA with all it's "kid" activities. Had a family cookout and took full advantage of all the KOA had to offer. Ofcourse along the way we sent postcards and made calls to the boy's Mom so she didn't worry and knew they were well. Too soon it was time to pack up and return to Illinois. Remember that morning all too well, during breakfast I told the boys it was time to head back to Illinois & their Mom was missing them. What sad faces!!! Brandon, the 7 year old, sad in silence for what seemed the longest time, then looked up at me with a bright smile and said.... "we can call her". It was SO difficulty keeping a straight face as Brandon was SO serious. Neither of the boys wanted to leave. Through the years our annual trip to Michigan was always the high point of each year, visiting many lighthouses, beaches, campgrounds in our travels. The "boys" are now 17 and 15 and we still talk of all the exciting times at Mackinac & Michigan.
