Hey gang... say... I live in North Dakota and the snow is starting to fly. My 8 Month old is getting marks everyday along with her force fetch sessions. My question is... do you guys switch to the half black and half white bumpers in the light snow conditions for visibility? I understand that one would not want to run ,marks in high snow conditions for the sake of safety, but what are your tips for running marks in less than ideal conditions? a.k.a. snow... thanks in advance...
