I live near the Marshall Gold Discovery Site in Coloma, CA. This is where the Gold Rush began when James Marshall found gold there in 1848.

The old Gold Rush town of Placerville, also known as Hangtown, has a neat old downtown with lots of history, including Hangman's Tree Tavern, which, if you look closely at the picture, has a man hanging from a noose out front (Tacky? Perhaps. Unique? Definitely!):

Lake Tahoe has some interesting historical sites as well. Vikingsholm is a neat old stone "castle" on Emerald Bay. Have not been there yet, but I hear the old Thunderbird Lodge is pretty neat as well.

The Lake Tahoe Visitor's Authority even has a cycling section on their web site:
