Hi Luc,
Barbara, Jaclin, Isabelle and myself will run the Upper Black on Saturday. Let's meet at the take out, at 10:30, as proposed earlier. We should be able pack 6 people and boats in the van. So shuttle is no problem (should be plenty of people there anyway)
We have a room somewhere close to Marmora and are happy to paddle with you guys on Sunday.
Dirk
