paper and phone list of all the scouts and their contact info; When we're out I'm responsible for all of them - and this includes getting them home or to a parental unit. ( which might involve as many as 6 possible contact phone numbers)
Great point. On outings we're supposed to have all the membership information, which includes contact info, as well as a hard copy of our emergency plan (and a couple other pieces of paper I'm probably forgetting!).
