One of the reasons we are bidding to host Westercon in 2015 is that it will be the 100th anniversary of the Panama-California Exposition, which was held in San Diego’s Balboa Park.
Balboa Park, in conjunction with History Pin, has put up an interactive map of Balboa Park with historical photos, including several of buildings built for the 1915 exposition. Â Mor information on this can be found at http://www.balboapark.org/historypin.
