I've been rained on several times on bikes, cars, trucks, planes, horses and other modes of transportation. Yesterday was the exception. Got caught in a tremendous downpour. I don't care what rain gear I had on, I got soaked. Felt like I had an unexpected enema! But the spyder did very well in handling and for the most part, stayed dry. Must admit had a little dampness in the trunk, enough to get few papers wet. But folks, I don't know how anything could've stayed dry in that storm. I will examine the gasket. Be safe.....
