My husband and I are leaving in 10 days for our first road trip. We are driving from Syracuse, NY and going to Nat'l. Parks in South Dakota, Wyoming, Utah, and Arizona. IF we have time, on our way home we want to go to San Antonio,New Orleans and Memphis. We know that Utah will be the "busiest" state, because of 4 Nat'l. Parks that are spread out. We have a month to take it all in. My question is: will we have enough time in a month to take in these states?? If not, we will stop at Arizona and come straight home from there and not see TX, LA and TN. Thanks for your help!
