If you’re reading this, you’re spending too much time indoors this summer, says Coca-Cola. The company is taking its America Is Your Park competition to a new level with innovative options to vote for your favorite American park while you’re enjoying the summer sunshine.

Last year Coca-Cola ran an online voting contest to determine which U.S. parks were the most popular, awarding a $100,000 grant to Bear Head Lake State Park for the top title of America’s Favorite Park after they received 1.6 million online votes.

But this year Coca-Cola is taking the voting outdoors. Voters get one point for voting online, but if they use a smartphone or tablet to check in via Facebook at their park, they get 5 points. Five more points are awarded if voters upload pictures of themselves and their families at the park.

Associations could implement this strategy in their competitions as well. They could use social media check-in technology such as Facebook or foursquare to let voters at a conference choose the best new product from the expo hall or the best presentation in the education sessions.

What other ways can your organization implement more interactive online voting techniques?
