Thanks to my colleagues at U.C. Davis for a wonderful visit on May 10, 2013. I had the opportunity to meet a large group of students and faculty who attended my seminar. Thanks to Prof. Lisa Aultman-Hall who has been visiting Davis this year on sabbatical, I had a wonderful tour of the city's excellent cycling infrastructure. Seems like Delft with wider streets and no canals (and no stroopwafels!).
