Good read Devin shanks is definitely a character but I will have to stick with the Masters as No 1, however personally I rate the PGA ahead of the British Open.
I know,I know the whole ugly American thing but IMO outside of ST. Andrews and Murfield the Rota of courses is not all that appealing.
I know I am in the vast minority who would rate the PGA ahead of the Open championship.
Spent 2 days at Oak Hill last year at this time, got to see Duff tie the major low round mark. What a great, classic Golf course. The PGA is held some all time classic golf courses.....Medinah , Southern Hills , Riviera,Oak Hill, Oakmont ,Oakland Hills, Hazeltine.
.A great list of classic layouts.
