As many people noticed, the blog went down completely. It generated a kind of fatal error and my host shut me down as a precaution (the error affected their MySQL database). I have contacted them and they have opened the blog again ... but I haven't had word back on the error so it's not really resolved yet.
So, for now, comments are off (error originated in comments DB) and posts won't be forthcoming until I get the exact info and fix. Sorry for the inconvenience everyone.
In the mean time, here's a photo from our many night rides in Shanghai. This one is much clearer and well thought out than the usual ones as I had help. Thanks, Micah!
