I've visited most of them, but Shiloh much more than the others due to proximity. It is naturally preserved, and a beautiful place, especially when the peach orchard trees are blooming.

Gettysburg has a special aura due to its size, impact, preservation efforts [tree cutting etc.] and always has an impact on me when I visit.

But, my favorite choice would be any of the several fields of conflict in the Shenandoah Valley. Its been a while since I've had a leisurely trip through the Valley, and hopefully "progress" has not stolen the natural beauty.

In so many places, the Valley appears [in my mind] to be just what it looked like during the war. What a treat to watch Spring work its beauty up the hillsides a day at a time.

Also stirs up some ill feelings that I harbor against the bully boys-- Custer & Sheridan.
