Hi C.!
One thing you might want to check out is your local library. They usually have a pass program to local museums/zoos/parks/etc. where you can get in for free or for a large discount. A lot of the libraries network together, so if your branch doesn't have something available, another might! I've gone on some great outings using these passes - Mystic Aquarium in CT, Roger Williams Zoo in RI, the Ecotarium, Children's Museums, and a lot more!
Have fun!!
