The problem with junk is that you get attached to it. For some people this isn't a problem but for others it reaches the level of addiction. I have seen talented people completely short circuit their potential bonsai career by adopting every ophran and waif to come down the pike. You won't learn anything from this pine, and if you did it would just increase your chances of getting stuck. Good bonsai beginning material is CHEAP! Start by limiting your searches to traditional species with at least some potential. Bonsai is hard enough to learn with good material, starting out by doing heroic rescue work on dubious material only increases the chance you will never get there.
Sorry, if this sounds mean, but 90% of the material posted on websites like this belongs in the garbage can on in the landscape. This wonderful resource is simply inundated by junk collectors. I have seen professional after professional abandon the web because of this. One of the things that drew me to this website is that there was a lot of high quality material with a decent level of discussion. But slowly we are reverting to the level of all the other forums. It's our choice, but I would hate to see it happen. It must be possible to have a substantial forum without the dreariness of AOB or KOB. or the clunkiness of IBC. And don't get me started on birthdays!....
To paraphrase Walter Pall, let's not be afraid to call a spade a spade.
