The high seats are ok, but superspeedway viewing generally isn't my cup of tea. Just one asshole's opinion, though. If you ride in/out you might be better off than in a car, if you're willing to be, um, adventurous.
Overall, if you just want the speedway experience, its ok. It's fairly remote, however, you'd likely want to stay in say, WilkesBarre/Scranton or Allentown, unless you camp. No infield camping that I'm aware of, but plenty of stuff in the area.
Overall, I had a better time at Baltimore, and I've been going to Pocono since the CART days in the 80's-mor fun then, hot pits during qually etc
