Hope you enjoy! My sister and her family are in western PA about 3.5 hours away and usually make a day trip out of it. I don’t think they made it this year though.
I checked google maps and it’s about a 3 hr. drive for us, we live in north western Jersey. Plenty of places to stay overnight in Gettysburg, close to the festival. I wasn’t really impressed when I first found out about it until I went on the website. Hot rods, ribs and lots of other food, apple everything, and I would also like to see Gettysburg, never been there either.
