Boston is one of a very small number of cities which could hold a Worldcon exclusively using local talent.

We have a lot of fans in this area, but the needs for a Worldcon are not just for the willing -- they're also needs for specific skills, management experience, knowledge of previous Worldcons, etc.

Being foolish enough to believe that all of the talent you need to run a Worldcon is located in your city is a really, really bad idea.
