If your purpose on this trip is to suffer and be uncomfortable then pay no attention to what follows, and please don't come on the trip.
Conditions for your consideration: The average highs in May in the area are in the 50s and the lows in the 30s (Farenheit). Averages being what they are, this means we could see a blizzard. Fairly strong winds are to be expected. This is the dryest time of the year in Alaska, but Alaska is a wet place. Wind chill and hypothermia are considerations. Some of the terrain we will traverse will be quite rough.
Necessary gear for every individual (remember - this all has to fit in the boat):
Tents: The most critical thing is that these be compact, lightweight, and able to stand up to a strong wind. You might want to also remember you are putting these up and taking them down everyday. We will cram as many people in each tent as possible.
Side-zipper duffle bags are easier to transport, stow, and get things in and out of, and are recommended.
Other group gear:
GPS units, maps, light weight tarps, group first aid kit, group
radios, cooking gear, readings.
