Having played several great short par 3's, The CC one should be in the conversation, but the greatest, that is a possible reach. What about LACC 15th, LACC old 17th, NGLA 6th, LuLu 4th, Glens Falls 9th, Myopia Hunt Club 9th, and certainly not least, Old 14th at Engineers.
Of course I am biased, but I think Engineers is even better than TCC's short hole. It has not had major competition since the 1920 US Am. But it was at that event that scores actually ranged fron 2 to 20 in the qualifying. In recent years, the hole played comfortably above bogey during qualifying for match play in the Long island Am, and the most difficult pins were saved for the later rounds
