I dreamt that the outing club was having some river trip, but it was on inflatable rafts. People were picking out their rafts and floating around in front of the building. I had signed up for the trip, apparently (since I was there), but I was a little late showing up and didn't know if I needed to go get a raft myself or if I could just take one that was floating by. The floating by ones seemed to mostly be claimed already.
