Denver is a great place too hold this years conference. I not only suffer with CH, I also suffer with Asthma.. I camped out for a week in Denver a few years back and had no problem until I attempted to go up to Pikes Peak with some of the other campers... That was a no, no... So they brought me back a pin (smile)... My headaches were no different in Denver, than they are here in Illinois... Ladyluv - aka Mamahlf
