Great to see you back, Pat. Hope all is well.
As the to the question, 4 has always been one of my favorite holes at Spyglass (played it 20+ times), but 1, 2, 8, 11, 13, 14, and 17 are cool too. Got my 1st hole in one on the 12th in 1979, but it's just an OK drop shot. Haven't played many other RTJJr. courses in the past and don't really care too in the future. He did a good job at a great site at Spyglass a long time ago. That's enough for a man's life time's satisfaction.
Rich.
