I will be willing to run sweep for one of the medium groups, but only if the lead is knowledgeable of the route. I know the roads a little but my knowledge is specifically to 78, 56, and 93. I don't recall ever riding on 669 or 691 at all. I will download the route details for my tank bag tomorrow night just in case, if im not needed that's just as well to. Gives me less responsibility
