Any exceptions to the practice are noted in the trip description. Call the trip leader at least two days before the activity to establish the number attending and to explain capabilities required for the outing in question. Failure to call may result in not knowing about cancellations, rescheduled departures, etc.
Guests are always welcome.
This will be a matter between you and your driver. Outing Rules Leaders will suggest guidelines that apply to their outing, take calls, and lead the outing. The leader is not a guide. For those who are not ready for strenuous trips, it is best to start off with easy hikes and work your way up. Raingear is also recommended for all hikes.
