Jag's trip east resulted in a perfect photo of the type of sideskirt I have been looking for...one with minimal flat surface. The lighting suggests this. Thank you, sir! But, just to be sure about this observation I want to confirm the concave design...am I right about this? Past experience here in salty road Michigan revealed disgusting deposits of road salt and dirt on the flat board type of skirts I ran before. And, at the interface of the rocker and the sideskirt, the debris collects itself and can only be removed with water spray....not fun when temps are below freezing.
