If you're not on Facebook and you hate Facebook, like me, then you've come to the right place. Over the years I used MB many times to find paddling partners. This place isn't what it used to be for CO paddlers but keep your eye on it and don't hesitate to reach out to people, you'll find some good folks. These days I often solo kayak Class II-III and I often just meet people when I'm getting ready at the put-in and run with them. If you're really itching to get out and you haven't found a partner it might not be a bad strategy to just hang out at the busier put-ins and see who comes along, if you have the time.
