Yeah this was my point.They do have a helicopter at the Snohomish County SAR but they advised us that we shouldn't count on it and that we especially shouldn't count on it being sortied very quickly relative to a suburban ambulance service. I think that's one of the reasons cited for Emergency Shelter being part of the 10 Essentials. If you have to do extensive first aid or one of your party is incapacitated you will probably be overnighting in the backcountry here even if you're on a day hike or climb.
