I actually checked out this new shop in bushwick a month or two ago...

The girl who runs the place was pretty chill, however they didn't have much stocked yet. She told me she that way more stuff was on the way. By now I bet they're up and running. They actually have free Q & As and repair lessons once or twice a week, which already just shows they're patient and willing to pass on knowledge instead of letting people stupidly go back to them to have work done that they could do themselves. In general, they seem to have a pretty good attitude, I think.

Sadly, it's kind of far from my hood...
