SAN ANSELMO, Calif. (KGO) --It's a tale of two cities in the North Bay: Guerneville and San Anselmo. It began as a night of heavy rains evolved into a morning of fear, near misses and also some serious damage.
The weather came close to sweeping parts of downtown away. At 7 a.m. the San Anselmo Creek reached 14 feet and seemed destined to turn the center of town into a riverbed, once again.

"It is brutal," said Kacey Gardner, who had ten minutes to move all her stuff at her store, Tumbleweed, to higher ground for the fifth time this rainy season.
"I have been open for five days in January" she said.
In Guerneville, even the community that says it has seen everything water can bring expressed surprise.
Fawn Harbour never expected to be thanking members of the Russian River Fire District, but that was before heavy rains turned into high waters, and then those high waters turned her house into an island.
Fire fighters has to walk her out this afternoon and it's not the first time she's been flooded this winter.
"This is three or four times, and this time, it will rise up into the houses because the creeks are coming now," she explained.
Creeks coming, landslides falling, and even roadbeds being eaten away from below.
It's the best of times because it could have been worse. And the worst of times because, after today, we wonder, what comes next?
