Tennis, like fishing, is better with a partner and extremely embarrassing with one's head caught in the net. Snag some friendly competition with today’s Groupon: for $10, you get a three-month membership to the Tennis Denver branch of the Tennis League Network (a $20 value), an organization that helps match local tennis lovers with playing partners.
The Tennis League Network operates like a very specific social networking or dating website, but with the sole intention of pairing up tennis lovers with potential playing partners. See how it works here. After registering with the network, subscribers will be connected with 20 nearby men and/or women, matching individual skill levels to create complementary duos. The partner program is split into playing regions for North Denver, South Denver, Golden, Lakewood, Littleton, Englewood, Aurora, and Westminster, allowing racket-brandishing participants to find a dedicated partner with whom to hit the tennis courts or clubs, and work on honing serves, volleys, and McEnroe-inspired racket spikes.
