I have been enjoying surfing around NY on Google Maps and I have looked up the subway system. It appears to end at Jamaica, if you are west of Jamaica on Long Island, it looks like there is no subway to connect to the UkeHut, it looks like you have to drive or walk or ride your bicycle. If its a 40 minute drive, its not going to be a lot of fun. I have never been there so I can only follow what is on Google Maps.
The StreetView feature must have been photographed on a Sunday or holiday when the shops were closed, the Uke Hut is just a steel roll-a-door on a dull brick building, easy to miss if you are not awake. The parking does not look too good either.
Personally I would be trying to get off the island and to find a better place to live. It looks like the only way to go anywhere is via the traffic mess of NYC.
