The crack of the bat and the roar of the crowd can only mean one thing: Opening day at Coors Field is upon us. It's that time again to head out to the park and watch your Colorado Rockies put the hurt on the out-of-towners. Play hooky and catch a day game or take the weekend and spend it in Lodo. Either way, enjoy the season and all the finer points of it, ball park concessions included. Nothing, and we mean nothing, tastes better than a hot dog at a game. Savor it, and follow these simple tips to eating healthy during your favorite summer outings.
