Fewer people are reporting sightings of the legendary Loch Ness monster in Scotland, prompting concerns that skepticism about its existence could threaten tourism in the region. There have only been two reports of sightings this year, compared to three in 2006 and much lower than a decade ago, when the annual number sightings was consistently in the double digits, The Times newspaper said Saturday. "It's becoming a potential crisis," said Mikko Takala, 39, a founding member of the Loch Ness Monster Fan Club who runs four webcams on the lake's north shore.
