Vicksburg - not terribly easy to get to, but worth the miles over the dusty, winding, bumpy road up the mountain.
Here's a little history from Wikipedia - especially interesting is the information about the trees, Balm of Gilead, lining the lane.
"Vicksburg was founded in 1867 after prospectors from Leadville, Colorado camping out in the Clear Creek Canyon lost their burros. The burros had wandered down the creek and when the miners found their pack animals, they discovered gold in the creek bed as well. In its heyday, Vicksburg had a post office, school, blacksmith, two hotels, two billiard halls, several saloons, a general store, an assay office, and a livery stable. Early miners packed in Balm of Gilead (balsam poplar) trees on the backs of burros and planted them to line the street. The trees still stand today and are watered by ditches leading from Vicksburg Creek into the town. The ditches were dug on either side of the street to provide a water system; wooden boxes were built in the ditches to keep food cold and provide water to fight fires."
