My last ten:
St. Catharines G&CC (multiple rounds), St. Catharines, ON, Canada
Muirfield Village GC (x2), Dublin, OH, USA
Wedgewood G&CC, Powell, OH, USA
Scioto CC, Columbus, OH, USA
The Medallion Club, Westerville, OH, USA
Longaberger GC, Nashport, OH, USA
Glencairn GC, Halton Hills, ON, Canada
National GC of Canada, Woodbridge, ON, Canada
Bethpage State Park - Black Course, Farmingdale, NY, USA
Southampton GC, Southampton, NY, USA
Of those ten, using my own scale, I've played one 9, one 8, two 7's, one 6, two 5's, two 4's and one 2.
This list takes me back to May 24th and it's almost not fair to stop at ten choices, especially since my 11th course was played the same day as my tenth (Southampton GC)
Interestingly enough, my 11-20 list might be a bit stronger, with two 10's but a couple duds in the mix too.
