Have you heard about GOALS (Get Outside And Learn Something)? We're a nonprofit organization whose mission is to "inspire exploration in youth through multi-day wilderness river trips." I'm a long-time commercial river guide and middle school teacher, and started the organization after too many returns from summer break to hear my students talk about spending their entire summer in front of video games. You could get your daughter, and a group of her friends, out on Deso, Cat, Yampa, Lodore, Westwater, or even the Main Salmon on a commercial trip for considerably less than their advertised rates.
Check us out at G.O.A.L.S. - Get Outside and Learn Something, or have a look at a slideshow from a Deso trip last year at Clear Creek Middle School Outdoor Education - let me know if you've got any questions!
