Build a Basement Golf Course
By Allan Carpenter POPULARITY of miniature golf has brought the game right into the basement in the form of a knockdown course that can be picked up and stored away almost as easily as you would a game of croquet. It's an exciting game the whole family can enjoy the year round—from the youngsters on up to the avid golfer who will find it good practice in keeping his putting eye keen. Standard putters and irons are used and scoring is done as in real golf, penalties being counted as strokes. As for space, most basements, especially those with compact heating units, will accommodate the "concentrated" nine-hole course pictured in the illustration above, but, where there's only a minimum of space, a lot of fun can be had from a much smaller course. As each green is complete in itself and lightweight, the course can be quickly set up. Most of the greens are fairly shallow to permit stacking them in little space when not in use. Where yard area is sufficient to permit an outdoor course, a suggested layout for an 18-hole one is given in the plan view on page 197. Construction of nine additional greens is given to supplement the nine shown above.
