Tee areas, green areas and rest areas(shaded or non-shaded benches). Then any thing that was a snack shop/bar/19th Hole/ then a pro shop area. Any old water hazards. Old balls are worth money too. There is an old abandoned course less than a mile from me. It is the boundary of a very expensive housing area. Don't know if it has ever been touched, but it is private property. The old Holiday Hills Country Club from the 1930's. Clubhouse burned down, course closed during depression I think. We belonged to the swim club(pool area) in the 50's. Cool old place. ALSO, since I won't go to jail now. I used to play Brackenridge Park golf course here for years. Built by Tillinghast in 1917 or so. Used to find arrowheads, old balls(dried ponds), old club heads all the time. old coins, gave them to the starter so I could play anytime. There's tons of stuff out on those courses to discover...
