Every outing needs one designated person to attend that outing, and usually it's the sponsor. If the Events Coordinator is sponsoring an event for you, it is still your responsibility to be in attendance. Nothing is more discouraging than to have someone bring an idea to the meetings, encourage people to attend, publish a date, and not show. I want to attend an activity in the newsletter. Call the sponsor listed in the newsletter article.
Some trips require a deadline for reservations and the sponsor needs a head count.
Even if you are unsure about your attendance, call and say you are considering. The newsletter is the primary means of disseminating information. They occasionally publish some of our events in their calendars and the sponsors first name and phone number will appear. It varies according to the activity. Specific gear probably will not be addressed in the article but the sponsor will be able to tell you what you will need.
