Today I came home from my ride (in the rain) with itchy, burning welts over large areas of the inside of my legs, ankles and lower belly. These are the areas that get the most water thrown up from the road (in spite of having a dandy set of fenders). I've noticed this a couple of other times this winter after really wet rides soon after snow has been on the roads. It's almost like a burn and is very painful for about a half an hour after the ride. Is there something put on the roads to melt the snow that burns skin? Anybody else experience this?
