Many clubs choose ACA affiliation for insurance reasons, and the ACA home page lists all member clubs by state. It is all volunteer, and has it's own boats, equipment, a van and a trailer. Most of their trips are oriented toward class I-II rivers and lakes, and are either car camping or canoe camping. There are one or two weeklong trips in the summer. Trips are usually on the 2nd weekend of each month.
Volunteers organize the commisary, but tasks are shared during the trip.
This includes a strong canoe program, with classes from flatwater through whitewater, formally and informally organized trips, and rental equipment. Volunteers organize and teach all OU classes and outings, and activities are run cooperatively. A large percentage of the involvement in the canoe program is from non-UCSF people, many from beyond San Francisco city limits. There is also a rafting and whitewater network organized by David Delfiner at the same number. OU trips run the gamut from flatwater to class III and higher whitewater.
