The free movie at the visitor center provided a good framework for the visit. Growing up in the northeastern part of the country I wasn't familiar with much of the history in the south. The driving tour itself wouldn't be of much interest if you don't pick up the map at the visitor center and read what was going on at each numbered stop. As we progressed farther into the park and got a feeling for the proximity of the opposing troops we enjoyed the experience more.
We especially enjoyed the Cairo exhibit at the far end of the battlefield. The restored vessel and the artifacts inside the museum post there gave real flavor to the time period (I wouldn't have guessed they had Lea and Perrins back then!?).
