Even after seeing the sign 'Lee's Ferry Arizona', Craig and Lucy believe the fully inflated and tied-up raft labeled FORT LEE COMPANY (in huge letters) is an Army surplus item, and not the property of a private rafting company. The Fort Lee Company was a real river rafting company that operated until 1983, when Wilderness River Adventures took over.
Lucy punctures the raft which then deflates, but the next morning it is patched and fully inflated again.
The borrowed camper has the same California license plate number (WHM-560) as Lucy's car seen in "Lucy Helps Craig Get a Driver's License".
Lucy throws one of the life vests overboard to Kim, but it floats away. Somehow, however, there are still enough life vests on the raft for everyone later on.
