No bad options
I agree with Badaz. Why make it an either/or? I'm a big fan of CW, but I know a number of PPWC members and they are great guys. So rather than trying to run down a great club like PPWC, I'll tell you what I like about CW.
First, CW offers lots of club trips, ranging from class I to class V. Second, CW has great winter classes, safety seminars, and instruction for all levels of boaters. Third, CW is a great place to meet boaters. We have River weekends on the Ark, the Poudre, the Colorado, and Powderhorn weekend down on the Gunnison, Taylor, Lake Fork, etc. Plus, training camp on the Ark is a great tradition and opportunity for learning boaters. Fourth, CW is very active in access and conservation efforts. Recent efforts have included testimony before the state house and senate, working with SWSI technical roundtables, defending kayakers wrongfully charged with trespassing, preserving access on the Lower Blue, and coordinating policy issues with AW. Finally, CW's fall and spring dinners are fun social events with great speakers, such as Doug Ammons, Pete Heller, Kent Ford, Nick Hinds, Kyle McCutchen, Evan Stafford, and Rebecca Glidden, just to name a few.
I check out PPWC's website on occasion and that club also has lots to offer. So why make it an either/or? Besides, you could join AW, CW, and PPWC and still spend less than you would for a day of skiing. Enjoy them all.
