Tamarack Golf Club
Today's Groupon gets you and a golf buddy 18 holes on the difficult Tamarack Golf Course in Naperville for only $50. Each Groupon is good for two people to play an 18-hole round together, so get a pair and a foursome together to hit the lynx for the price of a 2.6-some (meaning it's up to a 62% discount—weekday rounds are $55, weekends are $65). Golf with friends is the best kind of bonding; there's nothing like being out in the open air, hearing the wind blow through the beautiful old trees lining Tamarack's well-groomed fairways, and refusing to grant your compadres mulligans. The satisfaction of a well-played hole is amplified by one's sadistic enjoyment of your partner's three-shot adventure in the woodsy rough.
