My parents brought me their when I was about 10 and I remember it like yesterday... the battlefields, the Lincoln Train exhibit (some train ride movie thingy that was kinda cool), I remember them doing a re-enactment on one of the battlefields that was pretty neat to watch too. We then went to the Amish country after that (seemed like it was next door but I don't know how far it was), that was another very cool thing to do.
Gettysburg is great to tour and the new visitor center / diorama is a great upgrade from the previous one. We have been going there about every other year for the last 10 ~ 15 years. I get the most enjoyment from the reenactments and sutlers setups but there is something for everyone that has the slightest interest in history of the country.
I was real fortunate being raised in Upper Black Eddy above Doylestown, Pa off rt 611 in the foothills of the Pocono's. We were real close to Washington's Crossing/ Bowman's Tower--it was close enough to BI-cycle to as a yute--LOL It was our own lil playground & as kids, we used to do our own re-enactments--my interest in this Countries history has never waivered since. As a father, I made sure all my kids got to experience many of our Countries historical sites--
If only the South had not been cursed with slavery our history could and probably would have been very different and for the better.
Just like today known problems got put off with makeshift compromises until they reached the point of cataclysm.
There has never been a shortage of smart clever people to run things, yet holocausts remain with us. My lifetime has been continuous war interspersed with short periods of recovery. Solutions remain beyond our intellectual ken yet it is the only tool we have which seems to indicate there is something we do not know.
