San Francisco and Miami are the finalists to host Super Bowl L, the half-century anniversary of America's biggest sporting event. The city who misses out on hosting the 50th version will square off with Houston and Reliant Stadium for the 51st in 2017.
If successful this would be Miami's 10th Super Bowl, the San Francisco Bay Area's 2nd. An approval for Miami would likely require some updates or renovations to Sun Life Stadium. An approval for San Francisco would show a great deal of confidence in the 49ers who have just begun construction of their new Santa Clara stadium, which is scheduled to replace Candlestick Park in 2014.
The 49ers new stadium is being built 40 miles south of the city of San Francisco. Should the team succeed in their bid, it'll be the 2nd time they've hosted the event outside they're home field. Stanford Stadium hosted Super Bowl XIX in January 1985, a game in which ironically enough pitted the 49ers against the Dolphins.
Lastly, if San Francisco secures any Super Bowl, it'll be interesting to see if events are divvied up amongst Santa Clara, neighboring San Jose (California's 3rd most populated city behind Los Angeles and San Diego) , and namesake San Francisco. Early indications are that San Francisco and Santa Clara are the cities that are in on this together.
