Good stuff. I went to a GS this last week end. Picked up a couple books and the lady said make an offer for them all. I was just clowning around and said 20 bucks. She said sold. Crap I was just kidding. So I bought 10 good size boxes and almost did not fit in my SUV. Most went to GW. A lot of German and vintage college text books I kept. May make my 20 back if I work real hard. After I bought the books the lady said I have a lot of old German books but have a translator coming over to look at them. Turns out the owner was a pilot for the Germans in WW2 and migrated to the USA after obtaining a degree in Physics. Hard telling what she will have.
