Ray, Tracy Arm excursion is one I'd highly recommend to anyone going to Alaska, (as well as a side trip to Victoria to see Butchart Gardens). Even though it rained on and off, we got so close to the glaciers, and they are different than Hubbard....darker blues, and he backed the boat right up to that waterfall.
I hope other MUSH'ers will soon find time to post their pix!
