First, I’m denied entry to the local YMCA yesterday night since they have a gas leak (I noticed the PG&E truck out front, but I thought it was just doing routine maintenance). Then, this morning, I hear they shut down BART for awhile since there was a computer error. These little breakdowns to our infrastructure can really mess things up, and lately, I keep getting reminded that the 100th anniversary of the 1906 San Francisco Earthquake is coming up.
