Years ago we were trying to find the cheapest things to do living in NYC and so I came up with an idea to create a hashtagged list of things on Workflowy. Any weekday or weekend, depending on the weather or our mood, we could find something cheap to do.
Anyway, the list grew and years later when I remembered that I had it, I decided maybe I should make a website, so here we are.
I have not been to all of these places. This is just a list. There is no guarantee of quality for any of this stuff, it's just things I found while researching and writing it all down for my own later perusal. In other words, proceed with caution.
There are highly subjective reasons for listing things. I'm trying to keep the list relatively cheap but that could mean many different things.
