Quick! What's the only public golf course within 100 miles of St. Louis that boasts bentgrass? Here's a hint: It's a links-style course that meanders east of the Mississippi River, with wooden bridges, quaint lakes, wood-tie bunkers and the occasional giant cottonwood. Yep, with handsome views of the Gateway Arch, Gateway National Golf Links is the sort of course you'd expect to come with a hefty membership fee for the privilege of playing its rolling hills. But like so many great institutions the Library of Congress, the Museum of Modern Art Gateway National is open to the public, meaning shlubs like you and us can play it any old time we want. Regular greens fees are in the $40 to $60 range, with discounts for oldsters and during off-hours. Private standards, public access. What a country!
