last year we had an annual pass to the zoo and science center.

The zoo membership was definitely worth it and I just renewed it yesterday. If we (dh, myself, ds) go one more time, we've already recouped the costs. (I think last year we went at least 5+ times).

The science center was a waste because we went once and haven't been back since (it's a lil out of the way and weird hours).

I'd get one at the children's museum, but it's over an hour drive away and we haven't even had the chance to take DS because we're rarely ever out that way.
