Grand Junction, Colo. (AP) Whether it's something in the water or the grooving sounds of country music, the aftermath of what one health officials calls Grand Junction's “Woodstock” drives up pregnancies in this city each year.

Nurse-Family Partnership Supervisor Wanda Scott says referrals to her agency from the Mesa County Health Department quadruple every year after the music festival Country Jam. Scott told commissioners about the phenomena Monday during a presentation
called, “How Are The Children?”

Scott says on average the health clinic sees between 25 to 30 pregnancies a month. She says five weeks after the festival that number jumps to almost 80 a month.

The festival ran from June 26-29. Performers included Tim Mcgraw, Clay Walker and Sugarland.
