KC - March 28/29
Philly - March 28/29
San Diego - 4/4
Seattle - 4/4
St. Paul - 4/11
Denver? - 4/11
I would guess that the remaining sites have not nailed down something with the AHA yet.
updating, 12 sites now appear on the BJCP competition list.
3/28: Kansas City, Austin, NYC, Nashville
4/4: Philly, San Diego, Seattle, Zanesville, Sacramento
4/11: Denver, St Paul, Chicago
hopefully the dates stick but looks like all the sites are at least decided.
