This summer, like every summer, a cornucopia of Colorado grown foods are beginning to appear at grocery stores and farmers markets. Coloradoans will once again be biting into juicy Palisade peaches and ripe Rocky Ford cantaloupe. What is the primary ingredient of these delicious products? Water. Cantaloupe and peaches are about 90 percent water. And that hamburger – which might have come from a steer raised in Rio Blanco County – about 60 percent water.
