From Cunningham Falls State Park (that's where we camped), it's a mere 30-minute drive to Gettysburg. Since:
-- the boys and I spent several weeks studying the Civil War last spring
-- nary a one of us had ever been to Gettysburg (from my family, I mean)
-- our friends raved of their previous visit and highly recommended that we head that way
-- the 2 adult men in our party = history buffs... especially of the Civil War variety. A few hours at Gettysburg = music to their ears.
... we decided we really must go, and oh... I'm so very glad we did. The skies were blue, the mosquitoes were gone, the company was the best... we couldn't have asked for a better adventure.
Here's the abbreviated version~
