And CLEAN CLOTHES - well, everyone has had experience with that. But, if you are walking around with bright-white sneakers at the end of the trip, it is a sure sign of your husband having carried you on his arms for at least part of the trip - better put the plastic bags you have untaped from them to the garbage-bag near the canoe-trailer. Quietly and unconspicuously.

• Your co-canoer
• branches /bushes/trees/snags
• stones
• rain
• another canoe
• high and quick water - in fact the only non-humorous dangerous component of the trip, but fortunately rare enough on the Estonian rivers.
• rapids
• mud
• the car keys in your pocket
