I live slightly north of Philly and my sister lives slightly north of NYC. We are trying to find some neat places to meet 1/2 way between us. It takes me about 2.5 hours to get to her house. I don't mind driving a bit further, her kids are smaller so we are trying to keep their drive to under 2 hours.
So far I have looked in to Island Beach NJ which is 2 hours for both of us, which is doable. I just don't know how to find anything else! Google isn't helping much!
