It doesn't seem like too many visit the board from east of Harrisburg, so sorry if the WPa folks haven't been providing information!
Been there a couple times (a few years ago, back in my softball life, which I alternately miss and feel like I have emerged from an alternate mental state).
To get to the fields (at least from downtown), you drive through one of the poorer neighborhoods. You're in your car, but if that scares you, you'll be scared. It's not middle class suburbia. But I saw no problems at the fields.
And, yes, there's not much to do in the area, but I don't remember that much downtime at Eastern Nationals. I didn't think it was like full Nationals (where you get to spend days and days of money in Sterling or Columbus - lol).
