I've been doing a little volunteer work at a local thrift shop which has quite a large inventory of books. I can buy books for 15 cents ea.
If we should happen to meet in meatspace sometime, perhaps you might like to list some titles/authors for yourself & Bri.
Appreciate the offer, Dave. I'll give that some thought before the next Sierra trip this summer. Presumably you won't be in the vicinity of Death Valley next Week? I could put you to work . . . ;-)
