I agree with you Adair but: This summer I had a chance to make it through a number of nurseries in you part of the country and I was appalled at the paucity of material, and locations. Nurseries seemed to be very sparse and far between. However; the cost involved in the bonsai nursery means you have to find one, there is not one on every corner. If you desire to drive, walk or crawl on hands and knees, the distance involved could mean taking off a couple of days work. My nearest bonsai nursery is 35 miles away and she only deals with tropical trees. I don't think there is one nearer than Ohio, or Pennsylvania, either one at least Two-hundred miles away. As to bonsai clubs; there again they are not all that common, in in our case very often the material you may find here is questionable.
I don't mean to make this sound condescending but a couple of you guys seem to think dropping a couple of hundred dollars on a single piece of material is nothing. That's not true for all of us. I spent less that that on all of those Mugos I bought last summer.
