You should send your proposed trip to trips@canoecruisers.org - where one of six or so trips committee folks will pick it up and post it on the Club Calendar [you can do this yourself, it's easy]. They will also contact you to suggest they help send out an announcement to paddlers on the relevant list: Pick-Ups, Sundays, Weekenders, Weds Evening, etc
Also, look at Susan Sherrod's post at the bottom of these messages.
