Edited to add: Thanks all for the suggestions. I guess I should have been more specific, that's what I get for posting without coffee.
This is an ongoing thing for us every Wednesday. With the weather, we're looking for more indoor things. The kid loves the waterfront, and Finnegans, but we've already worn those out.
We'll probably do either the library or the museum (didn't know they had a kid area) for today.
Any other ideas? I'm all eyes/ears.
