We bought the "self auto tour" CD's at the book shop in the visitor's center. You just slip them in, follow the signs, stop when they tell you, and listen. The narrator tells you what you're looking at along with all sorts of extra facts. We really enjoyed them and loved that we could go at our own pace.
I do hope that the soldiers didn't look as happy as Luke does holding their guns!
We drove down with our friends, the Crutchfields. Those are their kids, Ivy & Lane with Luke & Caleb at the pizzeria we stopped at for dinner.
This wild flower field wasn't part of the tour or any specific battle site, but we thought it was absolutely amazing so we stopped to take pictures. Unfortunately we did not do it justice.
