In 15 minutes, St. Petersburg, Fla.-based Tour Links' portable golf greens are ready for putting practice. The grass modules come in a variety of sizes, starting at 5 feet long, and use a system of panels that slide together along with a polypro-pylene turf surface. A patented floating cup provides another realistic element to the units, which can be used indoors or out. Tour Links can be custom-made to fit available space; they've been used on cruise ships and helicopters. For more information, call 866/921-7888, or visit www.tourlinks.net.
