SMOFCon is the annual convention about running SF & Fantasy genre conventions, held in different venues around the world. SMOFCon 28 was held in San Jose, California, the weekend of December 2-5, 2010. SMOFCon sites are selected one year in advance. This is a presentation of a proposed bid for Philadelphia in 2012, delivered to the members of SMOFCon 28. The actual selection will take place at SMOFCon 29 in Amsterdam in 2011.
