Doug Sr and Bee:
Glad to get that info out there. I would say that as long as the Secor entry is stet, then no, that history is not common knowledge. At least not common enough. Impressions abound (until you get there, obviously) that the MR is a minimally exposed 3 (except for the E-ledges) and the Secor walk-off will go. And unless there is an explicit statement posted in the intro material, there will probably remain the (perhaps less prevalent) impressions posted that bushwhacking the willows will also go.
