Los Angeles may have lost out on the Olympics (to Boston!), but this is a city of opportunity. Today comes its next chance to welcome all the world: a World's Fair. An Indiegogo campaign was launched just last week by the appropriately-titled Los Angeles World's Fair, seeking $100,000 to build the first of several transit-accessible pavilions all across the city; so far they've raised a pretty impressive $41,000. If things go according to plan, the fair would run for two full years, from 2022 to 2024.
