I just found out about Wikivoyage today. I can't believe I did not know about it earlier. Wikivoyage is Wikipedia for destinations. I will use Wikivoyage extensively for this trip as it complements my cities pages.
I have a bonus city for this trip in April: Las Vegas. I am going to Microconf 2013 from April 28 through April 30. I'll probably spend one extra day checking out Vegas before heading off to Los Angeles. I'll also be at Adobe MAX the weekend following Microconf.
