I'm from NYC, and go to school in Ann Arbor, MI.
I recently lost my hearing, so I am just discovering NYC from the vantage point of being deaf after living here my whole life. It's actually pretty good! While I don't know sign language/ASL yet (though I am learning), I get the sense that the city is actually pretty deaf friendly. Most of the newer subway trains have signs that say the next step (as opposed to a guy speaking it who I obviously can't hear now), and people seem to be pretty receptive to writing things down or making it easy for me to try to read their lips.
In Ann Arbor, where I go to school, my college campus is really good too! When I graduate though, i definitely see myself going back to NYC.
