It actually got dirty BEFORE I put the flaps onIt hasn't really gotten much worse since then, and it's pouring rain out today so all that mud (thank god the salt is pretty much gone) is just rinsing off. Woot.
ahhh haaa!! that makes sense! i was looking at the heavier mud splatters trying to figure out how in the world that splash could get behind the mud flap like that. lol
