It will be helpful if each participant registers before the 2013 light and color meeting. You can so online. The cost is $250 for a primary participant, including meeting registration, lunches on August 5. 6. and 7, and the evening expeditions (including the riverboat trip). The cost for an accompanying person is $50. For discounted student rates, please contact Dr. Ken Sassen (ksassen@gi.alaska.edu).
