I never knew asbestos grows in the wild.

"CARSON CITY — The discovery of naturally occurring asbestos in and
around Boulder City is delaying work on a $600 million highway bypass
around the community while the state Transportation Department tries
to figure out how to deal with the issue.

“Is this a showstopper?” asked Gov. Brian Sandoval during a Monday
meeting of the state Transportation Board. “This was a bomb that was
dropped.”
