Our family of 6 traveled back to Kentucky/Ohio area each summer to visit relatives as I was growing up. We used suburbans and tents for several years, then a delivery van converted to a motorhome, then a suburban and travel trailer for the remaining years. The best choice was the travel trailer and suburban.
During the trips to and from we visited many of the historic and tourist sites across the country. My parents would have us research the areas we would travel and the places we visited. It helped to gives us a leg up in school because we had seen first hand many of the places teachers would discuss in history and geography. It is a part of my life that I still value. During these trips we visited all of the states in the Continental US plus most of the National Parks.
