It seems that it doesn't really matter private or public course, time has a way of changing this game, leaving only memories. With that said, some of my fondest memories of courses of yesteryear in no particular order.
Circle R in Wimberley TX, both the Meadow and the Hill, and I guess you could throw in the Back 50 where I threw an ace on hole 4 I think.
Circle R2 in San Saba TX, all three courses were great courses. Strawbale and Meandering Greenbelt were awesome, but I really enjoyed the Colorado River course.
Selah Ranch in Talco, Tx, another John Houck gem, and both Creekside and Lakeside were great courses.
Horseshoe Canyon in Jasper, AR, such a beautiful course.
I'll throw Copper Mountain on here because I've heard they no longer put it in during the off-season. The sites alone made this a must play.
Skyline (Lake Highlands) in Dallas, TX, was fun and holds a place as it was my first and I hit my first two aces there.
Same with Bear Creek in Grapevine, TX, not sure how many aces I hit there but it was a fun course as well.
Pease Park in Austin, TX, so many great views and always a must play while in Austin.
Round Top, TX, was a private course and Randon was always welcoming.
And I almost forgot Mike's place up in Gainesville, TX, another private course where I had a couple aces, both for money during invite tourneys.
It makes me want to take another trip to Trey Duece in Mount Vernon, TX, as that property has two John Houck courses, the Duece and Twist are both great courses. You can still play them but who knows for how long as the property is on the market.
And according to Steve, Shawshank in Huntsville may not be far behind, and that course is a great course as well.
There is probably more than the fourteen mentioned so just remember, when you get the chance to play a really good course, enjoy it because you just never know.
