Thanks for posting this! Sounds like a fun trip. I was looking at a similar trip, flying to meet a friend of mine in Chicago, and driving to those parks from there, but it didn't work out this year. Still hope to make that trip, maybe next year! The driving distances don't look bad for that loop. Seems like everyone agrees that PNC is one of the best!
Yeah it was a great trip. Luckily I avoided the rain by a few days.
