Good people making wise choices!!! Altogether not an uncommon situation (except for the rescue) when doing field work in Alaska. Glad to see they were prepared (mentally and with the gear) to make it an break in the normal routine, not an emergency. I have seen too many crews leave the sleeping bags, etc. at a drop off point because it was only a few miles to the site.
Helicopters have a bad habit of getting you out there a --LONG-- way from home and not being able to get you back. I would not want to count the hours and days waiting for weather or for the helicopter to be able to come back to pick me up. (Although there were some beautiful times there as well.)
