Sad to see it happen but that is how things are these days. It is not 1955 anymore, when nearly every kid would look forward to a hobby shop visit.
There are too many distractions now, too many other ways to be entertained, thanks to high tech games and other such things.
Here in DFW, two well-known hobby shops closed up within the last few years. One is left, near me, but his focus is mainly RC cars and making custom parts for the large RC jets. At times, I can't get music wire from him. His supply of balsa and plywood is about non-existent. I can understand why that is--not enough people are building anymore, so why stock what is not going to sell very well?
If the large RC jet craze ever stops, this particular hobby shop will probably close, too.
