Revisionist history is one of the great evils the liberals have done to this country, yet for every action there is a reaction - I am a homeschooler, and I can tell you that one of the main reasons for homeschooling is the biased history in the public school textbooks.
The day I read my son's geography textbook was the day I first started making serious plans to remove him from the public schools system. Eight years and several children later, I consider it one of the best decisions I ever made. And my boys are staunch conservatives.
Just avoid any of the guided tours. Get some history books pertaining to the specific battles and battlefields that you want to go to. Then hit the trail yourself. So far, every year, usually around mid-September after school has started again, I go to one battlefield and spend two weeks there, just prowling around. I've been to Gettysburg three times, the last time spending my two weeks going over the Devil's Den and Round Tops end of the field.
Ignore the pricks ... there are enough commercially-produced battlefield guides and history books to lead you on a merry chase for whatever time you want to spend there.
