we are in the same boat. finances are tight tight tight. I am itching to get out and do something. I'm really itching for a vacation, but that isn't going to happen any time soon.
I have found tons of free things to do in my area. the boston area has a ton of free things to do, something new each friday. there are other things like museums that are open to MA residents for free on certain days. we have a membership to the science museum that gets us in via reciprocity to lots of other museums/zoos. hiking is free, we do have a pool membership (our big splurge for the summer). we will likely do some day trips and pack picnics so we don't spend a lot of money going out.
its tough, but doable. some moms and I have been exchanging tips on free things to do.
I think we got so spoiled when we had more disposable income to spend. its hard for us to backpeddle sometimes and remember how NOT to spend. but we are trying to be creative and do our homework and such.
