Tedesco CC: My home course, home course to several generations of my family before me. I'm so fortunate that "golf" from the start was a Golden-Age course with an interesting architectural history...and fast, smooth greens!
Essex CC: First played it in an interclub when I was about 14, I almost lost my bag in the fescue at one point. This bridged the gap from the parkland course at Tedesco, to a more rugged parkland course with linksy roots like ECC. Playing it once each year from 14, I shot 119, then 89, then 76, and it continues to teach me things today at age 40.
Prestwick: Played many of the favorites during this formative trip, but it was Prestwick that was most fun for me. Links golf is almost a different sport, but helped my total knowledge of golf's roots, and the evolution to parkland golf as I know it in New England.
I've been lucky to see hundreds of courses since, but all seem to be variations of thoughts formed at the above three. I like innovative designs, and I don't shy away from controversial architectural ideas. One that always sticks out is Jim Engh's Four Mile Ranch near Pueblo, CO...wild terrain, no bunkers, shale mounds, wild green concepts, blind shots. I've played it 4 or 5 times now, and it's awesome!
