Congrats jptwins. I lived in Sacto during the 70s, and rode thousands of miles commuting, but took my motorcycle if I was going out.

I did my March century yesterday. A watershed century for me, as it is the first one I've ever done on wheels that I built myself (waits for applause to die down). I put fat tires on these wheels so I can stop riding the high traffic roads with the nice, smooth surfaces, and ride the back roads through the villages. I rode probably 75 miles of it sans helmet, due to there being zero traffic on those roads. A nice, relaxing ride.
Look what I found just a couple hundred meters from where I've been eating lunch almost every Sunday for the past couple years.

It's located in the midst of a massive tide pool, some 20 km long and a few wide. They harvested salt and traded it with their neighbors.

A clash of times. A local farmer, with the help of some friends, will soon plant this field, probably to corn. Each man is armed with a pointed stick with some heft to it, as long as he is tall. Standing a meter apart, they jab the business end into the stony ground, drop 4 or five kernels of corn in it and move on to the next hole, a meter away.

They've been doing it this way for thousands of years.
