I had to sign a form before I go to Sun Lakes State Park saying that I wouldn't sue Evergreen. Here are just "some" of the possible and impossible things that can happen to me in the four day window... Keep in mind that there has to have been a precedent for all of these, so all of these things have happened at one point or another...
GENERAL RISKS:
Please understand that when you participate in recreational or certain skill-developing activities both indoors and outdoors, you may be risking your physical being. It is impossible, however, to list all the dangers involved in any activity. The eventualities of injuries, death, or property damage are so diverse that no one can second-guess everything that can go wrong. Before you participate, you should become informed, as much as possible, about the inherent dangers associated with the particular activity in which you are to be engaged. Also, you should make sure that you are adequately prepared with the proper skills, equipment, and clothing to minimize these dangers. Here are only some of these possibilities:
You can become ill or die from: polluted drinking water; improperly washed eating utensils; snake, insect, or animal bites; exposure to heat or cold; personal health complications, e.g., strokes, appendicitis, heart attack.
You can also sustain injuries (sprained ankles, deep cuts, blisters, and other wounds) or die from: falling off cliffs; slipping off wet or mossy boulders or trees; being caught in avalanches or flash floods, colliding with a vehicle, boat, rock, log, or tree; being hit by lightening; hit by falling rocks; being attacked by bears or other wildlife; falling and receiving injuries from climbing tools, such as ice axes, crampons, and rope; becoming entrapped in a kayak, raft, or canoe; falling through snow into an underground stream; receiving burns from hot fires, gas stoves, or other instruments; falling into streams or rivers and drowning; flipping boats in rapids; and, with respect to indoor and outdoor, including clock tower, climbing, falling, being fallen on, tripping, landing on uneven surfaces, sprained ankles, abrasions, lacerations, blisters, fractures, dislocations and even death; as well as many other possibilities.
I think the only thing they've left off is "death by hoovercraft".
