We are heading to gettysburg next year for the 150 reenacement july 1-8 and camping at a campground in gettysburg. the reenactment is only the july 4-7 so I am looking for other things to do in the area. I was wondering if any of the PA people have any suggestions of things to do with a 3 1/2 year old. I was looking at Idawild but that is almost 3 hours back towards pittsburg. Sessame street is another almost 3 hours towards philly. does harrisburg have anything fun to do?? thanks for any suggestions.
