My wife stayed at the Hershey campground several years ago with a girl scout troop that they took to Hershey Park. She said it was a very busy rail line next door. If I would have known that at the time I would have gone along and stayed at camp all day and watched trains while they went to Hershey Park. I've already been to the park a couple of times anyway. Speaking of campgrounds, are there any others along the NS main that offer good railfanning? I prefer one with RV hookups since we have a 5th wheel trailer. I was looking at a PA Campground Owners Assoc. book and it lists one in Duncannon which according to the directions sounds like it is located on the same side of the Juniata River as the NS main to Altoona. There were a couple of others too including Mexico and Lewistown. Any info will be appreciated. Thanks!
