I live in one of the Boro's of NYC, Queens to be exact, I have just now checked after reading this thread, there are 12 networks within range of my laptop's wifi card, only 5 of them are secured, well 6 if you include mine, some people just either don't know or don't care.
i've cracked the schools network over fifty times in order to teach them to use something better than WEP. but they dont seem to take a hint.
using my toughbook, i get 23 wifi networks from the balcony. of those 23 i've managed to crack 19. the others are secured with WPA2. its kinda become a hobby of mine. i try to pinpoint whose access point it is. then i drop a note with the password in the mail box.
but my absolute favorite is my neighbor who has an unsecured wifi network and free file sharaing between his computers. i can enter his NAS and watch movies he has downloaded off the web.
