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.
