Chris, a suggestion is to look around or search the web for decoy collectors or clubs in your area. They sometimes sponsor shows and these are a great place to view decoys as well as visit with collectors who are really knowlegable in there hobby or business.
I recently was at one of these shows and I not only saw alot of decoys but other items like guns, books, fishing lures, reels, rods and items like seldom seen old powder cans.
Just a fun way to spend an afternoon!
