I would be remiss not to recommend Golden River Sports (www.GoldenRiverSports.net
) as a great retail location in the area and Renaissance Adventure Guides (www.RAGuides.com
) as a fantastic local kayak school.
However, the best advice I can give you is do not buy off the internet. Get to know someone (hopefully a professional involved in the business) who knows the sport and the awesome gear it has to provide. Everyone has a different opionion on what's best (what works for them may not work for you) so seek out the professionals and don't take blind advice. Demo. Demo. Demo.
Also consider joining Colorado Whitewater. It's a Club for paddlers and water-minded folks. When I moved to Colorado, its how I met all my friends, how I learned the rivers and how I figured out my skills and ability. Tons of fun...$30 a year to join plus you get amazing discounts at local retailers who choose to honor it. www.ColoradoWhitewater.org
