Don't know where you are in W.Va., but FYI, the
Potomac Bonsai Association's annual show and festival is coming up in two weeks at the National Arboretum in D.C. Lots of vendors (trees, pots, tools, soils etc), demos, and PBA show. May 5-7. Worth the drive if you're within three or four hours of D.C.
BTW, wouldn't bother with EWP. It's not going to teach you much, as it is pretty marginal bonsai material. Not many EWP bonsai around because it doesn't respond well, or consistently, with bonsai practices. In other words, frustrating to work on even for experts.
W.Va. and Va. have hundreds of species of trees and shrubs that ARE worth the time, from hornbeam, beech, blueberry, pitch pine, blackhaw, wisteria (easy to find this time of year because of the blooms--easy to dig out), the list goes on...
