I've been coming to the Franklin Institute since I was a child. I keep hoping there will be an exhibit that really wins me over- there hasn't yet. Went a few months ago with my 7 year old daughter, with new hope. Zipped through the museum, she did like walking through the heart (3x's).
The highlight continues to be the Tuttleman IMAX theater featuring speclacular documentary adventure type movies on a 4.5 story domed screen!

I love the Cape May Zoo much more than the Philadlphia Zoo! From birds to big cats, the boardwalk that leads you through a forested area out to see Sahara animals. Kangaroos and zebras. It's a wonderful place to spend the morning beofre hitting the beach.
