I feel pretty lucky as I have gotten to play 3 of the ones lised.
#12 Thunderhawk, amazing course and well worth the $ and spot at #12.
#13 Shepards Crook, also a great track, and much more forgiving than Thunderhawk. One of my favorites, but am surprised it is this high on the list to be honest....
#46 Brown Deer Park, great old course layout (i.e TIGHT) but you will not have a fun day if you spray the ball. Just hope with them loosing the PGA tournement that they keep it up in the shape it has been previouse years.
Will be playing Washington County (#35) this summer for sure as I have heard good things about it..
