I go to my local libraries alot...they all offer free storytimes and alot of them have craft time also --either free or sometimes just $1.00.. you can't beat that.
Also, we do Chuck E Cheese which is pretty good -- all games/rides .25....sometimes we don't even eat...we just go and play.
I've been on the look out too for out of the ordinary things to do. I live in the North HIlls. My kids are 4,5,7. I like to do different things and relatively inexpensive -- CHEAP!!!!!!!!!!! things! Let me know if you have any other ideas out in the North.
thanks
Sheila
