Mariela and I went to Colorado for a few weeks in May and June. It was an action packed two weeks, with Paddlefest and Teva Mountain Games. If you've never been to the rivers out west, you are missing out. We stayed in Buena Vista, CO and surfed/paddled: Numbers, fractions and the BV and Salida Playparks.
Stand up River surf is a very new medium. Kayaks have been surfing river waves for years but SUP boards are relatively new.
Badfish stand up Boards are available in a variety of sizes. 5' 11" to the 9' river runner. They are all hand crafted in Salida,CO.
See ya on the river
