I should probably elaborate...
My father, Roman Gray, was quite an archer and ran an archery shop ("Roman Archery") in the San Diego area during the 1970s. He passed away in 2007 and left a lot of stuff for us to sort through. Going through some boxes a few weeks ago, I found the book.
So, now I'm interested in getting the material that Howard Hill left behind, in print and on DVD. Not just for the "romance" of it, but because it is fun to read how he roamed to and fro with bow in hand.
