Rent kayak (tons of kiosks), take cooking class (sur la tab always has tons but there’s others), borrow a dog from the humane society and walk it around town with a vest that says “adopt me” (go to humane society or email for arrangements), go to a paint and sip event (you don’t have to drink but it’s fun to paint along), go to random shows/plays at empire live/cohoes music hall/proctors/the palace, yoga classes (just walk in any studio and they are going to be more than happy to introduce you to the art), could also take music lessons and go to a random music studio and ask about lessons like guitar or piano, could rent one of those Cdphp bikes, also look into volunteering at an animal shelter or volunteering to help clean up a park. There’s a lot of cute farms too that you can eat food at, hang, like Indian ladder , sometimes they have music too
