The rough in mention was indeed on Merion.
I don't know if it exists elsewhere - it probably does. I think a full power punch will get it out, guess no choice but to settle for a bogie.
borntobesting:#10 Merion is the main reason I started to play # 10 using my 3 iron off of the tee
I don't think that's a bad idea. It's an easy birdie provided you hit the fairway. I am always temped to go for the green but often hit a tree on land in rough/bunker. I do usually make birdie even from the rough but my DA is about 50% or less there, lol.
In a recent RG I got a double bogie on #10 because I was in 60-70%, round killer on first hole :(
