Have you heard of Knoebels? It's also in Pennsylvania. We found it 2 weeks ago and loved it! No parking fees, no admission fees. It's like an oldtime amusement park, you buy tickets to ride. The rides ranged from 75 cents to about $2.00. Sorry, not sure about the rollercoasters because DD10 will not go on one, even if you paid her!

.
It was very shady, they built around trees instead of cutting them down. We had lunch in the park (there are picnic benches if you want to bring your own), and lunch was $5.00 for 2 pieces of chicken (nice size), an ear of corn and a corn muffin.
I really enjoyed the day there and am looking forward to going back, which I can't say about sesame place or six flags. Knoebels was really a great park,

and cheap too! I think the whole day ran us about $40 and we still have $8.00 in tickets left!
