I guess paddling in the rain is not for everyone. After all you may already be sitting in a pool of water in your kayak seat, hopefully from the water you are paddling in ;).
Kayaking is a water sport and I believe I consider that from above and below. Of course the proper gear keeps one dry and comfortable most times, even in torrential down pours. I find it kind of fun actually knowing that all my gear is water tight and secure. My map case is sealed and secure, no water sneaking in to ruin the maps, my head is dry, and so is the rest of my body. Still some just don't like being out in those kind of elements. I find it actually therapeutic and kind of neat watching it pit the water's surface as it falls from the sky. The only issue I guess is if you stop for a break you can feel the coolness of the rain and its wetness being idle. At any rate paddling to me in the rain is as good as singing in the rain I guess and if you can do both then perhaps you really are in the right place in time.
