Not every duffer can afford to attack the Blue Monster at Doral, or even that all-sand monstrosity out there dreamed up by Greg Norman. Many golfers can't even afford to play a relatively modest municipal course, what with greens fees starting at $50 or more. No, golfers like us cast our lot at the low end of the sport. That's why one of our favorite courses is the nine-hole circuit at Greynolds Park, owned and operated by Miami-Dade County. For very nominal fees we get to enjoy nine fairly well-maintained holes, the most challenging of which is the par-five seventh: 521 long yards, with a bend to the right midway through. The green is an elevated island surrounded by sand traps. It looks easy, but believe us, it's proved impossible to par. The last time we played there, the double bogey on seven was all that kept us from the best score of our lives. Our entire lives! The course is open seven days. Here are the fees for Miami-Dade residents under age 62 (seniors get a discount): Till 2:00 p.m. it's $9.91; after 2:00 it's $6.63 (tax included); because they are renovating the greens, however, fees are $6.63 all day until around August 1. They also offer a special after 10:00 a.m.: $16.99 for two people and one electric cart.
