while in Richmond, I always took visitors here. Three preidents(yes, us southerners count Jefferson Davis) are buried here,as are Generals Jeb Stuart and George Pickett. A great place to spend a quiet afternoon, especially for the physically impaired. The driving tour covers all the notables except the tombs of Presidents Monroe and Tyler. this requires a short walk. Best of all, it's free.
Pros: No cost, lots of history, beautiful view
Cons: Map hard to follow, tour not well marked
