Centennial Way, a path in San Mateo County, is nearing completion, and I checked it out on Tuesday. The northern half isn't yet open - some of the hard surfaces and plants are still going in, and a few fences are still up, so I don't actually encourage people to ride it yet...but I made it through. I started at the South San Francisco BART, rode on the new segment (see the path without stripes). I then passed this sign, which says the southern part of the trail was opened in April 2008, and continued on (see the striped path). Walkers and wildflowers were out in force for a beautiful spring day.
