Lol, Lakers are old-school most-fun-wins frolfers. They are a hoot.
The St. Louis issue is that Carrollton, Sioux Passage, Jefferson Barracks, Logan, Woodland, Endicott, Wilmore, Quail Ridge, Konarcik, Rock Spring, etc. are all very good courses. None of them are great so nothing stands out as the "must play." A lot of very good courses but no great course makes planning where you are going a bit of a crapshoot. Until you play them all, it's hard to know what your favorites are going to be. Any combo is going to be a good day of golf, though. New Melle to me is vastly overrated but it's got potential and still being worked on, but it's way out West.
Foundation Park is the best in the area, but it's so far East that it's debatable that it's even in the area. It's so isolated that for me it's a one course trip to play it, and that's a bummer when you are course bagging. It's THE one, though. If you were going the St. Louis way and wanted to play THE course you have to figure out how to get to Foundation Park. Foundation Park is not an ace in the hole, though. The rough can get out of control and the long tees are not concrete yet. The signage is meh and there are long, golfless wanderings in the design. To recommend it, you have to tell somebody to drive out to the middle of nowhere to play a course that has some negatives that might make you hate it. So even talking about the best course in the area is messy; it's a lot safer to recommend Sioux Passage or Carrollton.
So there you go, clear as mud.
