I count at least 10 and maybe more. The problem is some of the tournaments are very popular from the fan and cities perspective.
Start with,
Waialae in Hawaii
Poppy Hills during the AT&T
Indian Wells, Bermuda Dunes during the Bob Hope are jokes
English Turn in New Orleans
Brown Deer
Then the TPC courses,
TPC Summerlin
TPC The Canyon
TPC Southwind
TPC Four Seasons
TPC River Highlands
TPC Avenel
The only 2 that are well liked are
TPC Sawgrass - being rebuilt
TPC Boston - also being rebuilt
Is it ironic that the only 2 that are well liked are being rebuilt?
