Who visits the bus and what do they find?what date is it ?

Ken Thompson, the owner of an Anchorage auto-body shop, Gordon Samel, his employee, and their friend Ferdie Swanson, a construction worker, set out for the bus on September 6, 1992, stalking moose.

'... according to Thompson, they found “a guy and a girl from Anchorage standing fifty feet away, looking kinda spooked.”

Neither of them had been in the bus, but they’d been close enough to notice “a real bad smell from inside.” A makeshift signal flag—a red knitted leg warmer of the sort worn by dancers— was knotted to the end of an alder branch by the vehicle’s rear exit. The door was ajar, and taped to it was a disquieting note. Handwritten in neat block letters on a page torn from a novel by Nikolay Gogol, it read:

S.O.S. I NEED YOUR HELP. I AM INJURED, NEAR DEATH, AND TOO WEAK TO HIKE OUT OF HERE I AM ALL ALONE, THIS IS NO JOKE. IN THE NAME OF GOD, PLEASE REMAIN TO SAVE ME. I AM OUT COLLECTING BERRIES CLOSE BY AND SHALL RETURN THIS EVENING. THANK YOU, CHRIS MCCANDLESS. AUGUST?
