Have you ever tried Disc Golf? I highly recommend the Zephyr Cove Disc Golf Course for an hour or two of cheap entertainment. Entry into this sport is very inexpensive and there is no cost to play the course each time. Few people take advantage of the Zephyr Cove Disc Course so you can get on anytime without a problem.

The object of the game is to traverse a course from beginning to end in the fewest number of throws of the disc. Each consecutive throw is made from where the disc came to rest after the last throw. Score is determined by counting the number of throws made on each hole plus penalty throws and then summing all holes. The winner is the player who completes the course with the lowest score.

The course consists of a series of holes laid out so that when the player completes one hole he or she proceeds to the beginning of the next until all the holes have been played. The player is provided with a teeing area from which to begin each hole and a target to complete the hole.- taken from Professional Disc Golf Association Website.
