The concessionaire of Yosemite National Park is seeking a PR manager. Keith Walklet, media services manager for Yosemite Concession Services, is leaving his post - 14 years after he arrived on a motorcycle. Walklet stopped in Yosemite on an 18,000-mile journey from New York to Alaska and got a job 'polishing porcelain' so he could finance the rest of his trip. 'I expected to be here one winter and it turned into 14 years.' Walklet is screening candidates to replace him but said that finding people with experience in PR, an interest in nature and the ability to work with state and federal agencies is not easy. Starting salary, which includes housing and health benefits, is $2,200 a month and increases with experience.
