SXSW dates hadn't been released yet at the time that Kinnon and I chose our date last year (same day we were engaged really). 2012 SXSW dates were announced in Feb or March 2011 and we had already started booking stuff at that point. It is happening a week earlier than people were expecting, as well.
Yes, it's still bothering me. But now I've confirmed that we couldn't have don't anything about it and am finally ready to let it go. :P
Very unfortunate timing all around.
