Hey ladies, I'm going to Philadelphia in late March/early April of next year. Our daughter will be very close to 2. What are some places we can drive to for fun? We have family in Allentown PA and Washington DC, so we will be going there. I've never been to New York and would honestly love it, but I don't know about going there with a 2 year old. We're thinking the DC Zoo, for one. What else? I've only ever been to DC on the east coast, so I'm trying to plan it for the adults, too!! Any ideas would be great!
