Histamine may be elevated with any condition that activates mast cells, and the release of histamine may be triggered by a wide variety of substances. An allergic reaction to a food is thought to be the most common cause of anaphylaxis.
Fur Rendezvous is a winter celebration of Alaska's fur trapping and trading heritage that is held in Anchorage each February. The Fur Rendezvous dates from the 1930s; the Alaskan fur trade dates back to the days when Alaska was a Russian territory.
Fur Rendezvous was canceled during the war years, but resumed in 1946, when the festival began to draw visitors from Outside, and has been held every year since. Since 1955 the event has been run by the non-profit Greater Anchorage, Inc.
