is for history

This summit is different from traditional health conferences. LGBTI Health Summits (previously in Boulder, Colorado; Cambridge, Massachusetts; and most recently in Philadelphia, Pennsylvania) have been described as nurturing retreats, exciting and intense think tanks, and an event of great enlightenment. Participants come away with a renewed passion for the cause, energized and inspired to tackle the problems confronting LGBTI health and wellness.

Chicago hosted the 2009 Summit, and Portland is set to host the 2011 Summit. Check this site for more info - it will stay up til 2011.
