DH and I would really like to take a weekend vacation somewhere with DS this year. Last year we bought our house and were unable to go anywhere. It would just be a weekend, and we would like to go somewhere we could drive to, and if possible, someplace where there may be something of interest to him, maybe an aquarium or a zoo. Not the city or Philly, we spend a lot of time in both places.

Any suggestions? TIA!
