Every software conference I've ever attended has been held in the city where the company is located, which is the ONLY reason I've been to Kalamazoo in the dead of winter. I do not understand why AC has decided to hold it in DC, unless there's something else going on there they need to attend, so this allows them to kill two travel birds with one stone (or one plane, if David's piloting).
Think they should just stick with having the official conference in Providence, and let us plan smaller conferences elsewhere. For next Spring, I'd vote for Seattle, Portland, Bryce/Zion, Denver, St. Louis or San Diego on the West Coast; NC Outer Banks, Charleston, or Savannah on the East Coast.
