RMCC has a Dolores trip starting Friday, see: Schedule
That Club gets a good turnout for their Colorado River Rendezvous in July, too.
I have a partner who wants to paddle FIBArk's long race OC2 this year.
I canoe the Gunny Gorge once or twice a year and prefer to go tandem. Should be tandeming the Ark a few times this year, too.
