I love to hike, and do it as often as my schedule, the weather, and my family allow. But I can scarcely imagine hiking all day long, day in and day out, for six months. Or four months. Or even a month. This is what "thru-hikers" on the Pacific Crest Trail do, year after year, and have been doing since the trail was conceived by Clinton Churchill Clarke in 1932. They train, plan, pack, practice, and finally hike all 2,663 miles of this trail that extends from California's border with Mexico to the U.S.-Canada border on the edge of Manning Park in British Columbia. Tahoma Audubon Society's first program of the year will be a free presentation by Gus and Elena Wimberger about their adventures while hiking the length of the Pacific Crest Trail this past year.
