...for those who might still not have snagged all the correct answers...
#13--the bayside angle of NGLA, taken whilst playing one of the truly great par-5's in the country
#14--the observant may have picked up on the "widow's walk" on the top, but this is the lake side angle of Shoreacres' magnificent clubhouse...
#15--Pumpkin Ridge and the Witch Hollow clubhouse & pro shop
#16--Kittansett, from the 18th fairway
#17--Exmoor CC in north Chicago, from the 18th fairway
#18--Lake Merced, taken from my usual location to the left of the 18th fairway
#19--This is indeed Erin Hills, with the clubhouse to the left and the cart barn/maintenance barn/ temporary snack barn to the right. They make a big deal about aiming at Holy Hill for some tee shots, and that is indeed Holy Hill just to the right of center on the horizon---not much to aim at, if you ask me!
#20--the sublime Baltimore CC, from roughly the 1st tee area on the East course...
#21--Philadelphia CC, from the 10th fairway
#22--the back side of the Rolling Rock Club main house, from the 1st fairway; the tower is on the opposite side as one drives in...
#23--the massive Pittsburgh Field Club building from below the 18th hole; the only thing many know about this club is the elevator from the 17th green to the 18th tee, but I thought the course itself was sneaky good...
#24--The Rockaway Hunt Club; under the flight path of numerous jets...
#25--Bellerive Country Club
#26--the view of the stunning Olympia Fields clubhouse, but from the 18th (I think) fairway of the South course...
