I noticed this about a week ago Don and I agree, a very pleasant addition. I posted and tried to draw the authors out as to their thinking on this aspect of the guide as the manufacturers in New York and Chicago are east of even oh, Ely! Perhaps a local Nevada sales agency could be the criteria? Glad to see the sane values to go with these pieces and I know they're in line with advice you've given me. I'm packing up a few trading samples myself for the trip but I did keep back the notched sample of a Chipco polished slick-finish, a surface I've not seen on a live Chipco chip.
