Organic foods and beverage maker Clif Bar is launching what it claims is the first geo-location Twitter campaign. The company wants you to send a geo-tagged tweet to @CLIFMojoGo the next time you're in a park, at the beach or on a trail.
Once the company has verified you are indeed outdoors, it will send you instructions to claim a free trail mix bar. You'll also be entered to win a Garmin GPS watch and other prizes.
