Title says it all.
I thought I'd found it at PlayBetterBluegrass, but they're out of stock.
I just did some searches and, dang. Folks are asking $180 plus for this book used. I saw one on amazon for a hair over $800 new. Best of luck to find one reasonably priced. I think I paid $20 for mine used.
I believe his daughters run the string business, but he retired. You may want to contact the (email@example.com). Who knows, they may still have some copies or the galleys in pdf. With the ask prices so ridiculous these days (they might not even be aware), you'd think they would republish in e-book form on Amazon and make some $$.
I've been looking for it for a long time as well. I borrowed a copy from a friend but had to return it. It's a great book but incredibly hard to find.
Cheaper than others, but still pricey when you add in shipping:
'Contest Winner !' 1 hr
'Crawler track ???' 2 hrs
'Don Reno Inducted' 5 hrs
