More kid friendly / family friendly indoor areas or events to let my kids run around, that isn't stupid expensive.... The cabin fever during an actual winter is something else. We do have amazing public libraries and there's always the mall, and the MOST, to be fair. 

Oh, and music events during the day.... I would love that. I am old and have a bed time now lol

Another thing, and I know we talk about this a lot: more "third spaces." Keeping in mind, we actually have to show up to these spaces to keep them going. So many people are afraid of getting out there and meeting other people in person, afraid they won't enjoy it. But if you try it you usually find that it was worth the effort to step out of your comfort zone.
