Last year's ballot measure to change the Oceanside Wastewater Treatment Facility's name in honor of George W. Bush is undoubtedly partially responsible for the influx of tourists checking out the inner-workings of the San Francisco sewage system. Newsweek reports that offbeat (and free) destinations are increasing in popularity, as we're all becoming more budget-conscious. A commenter on Newsweek also credits Discovery Channel's "Dirty Jobs" for demonstrating that weird and nitty-gritty places can be fun. Our most memorable field trip in middle school was when our environmental science class visited the local waste facility in the mid-80s. We were so ahead of our time!
