I second what Fred posted. I have been itching for a New England conference for years, and I have sent out appeals through Tech Talk over the last couple to have interested clubs raise their hands. Keep in mind that the AHA has 3 full time employees (Gary, Janis and Kate), and half of Jill Redding (Zymurgy). While they get assistence from other Brewers Association staff for handling the conference, it takes several dozen volunteers to pull off a successful conference.
There are about a half dozen critical factors taken into consideration when a bid is submitted, with about a dozen more prominent ones weighed in as well. Fred and I worked on an unsuccessful 2010 Michigan NHC bid, but we certainkly enjoyed Minnesota, along with the fact we were not hosting. Hosting is a huge committment, and while we were hopeful to acquire the conference (and will likely submit another future bid), we were able to relax and enjoy homebrews much, much more.
So, if you are in the New England area, and want to contemplate hosting a future conference, please let myself, fred, or any other AHA Governing Committee member know. Or Gary Glass. With the size and growth of the conferences, two years is now the normal preparation time to pull everything together. Commemerative brews, 100+ BJCP judges, easy transportation from a major airport, beer-friendly facility that can handle 1,000+ homebrewers, local support from pro-brewers, volunteer cellerman, club night organizers, etc., you get the picture.
