This idea simply takes current PSC shuttle practice and replaces vehicle shuttle with bicycles.

No, one driver doesn't carry 3 additional adults on their bicycle back to the put-in !  :)

Instead, every driver also brings a bicycle.   Drivers take their cars (with bicycles) to take-out and every one bicycles back to put-in (where PSC members would have to lock their bicycles).

Additional requirement:  At least one party needs to have 2 people so one adult can stay back and watch (guard) all the kayaks at the put-in while everyone else shuttles themselves back to put-in.

This would work well on multiple sections of the:  West DuPage River and Fox River.   It might even work on the Kishwaukee River (but there would have to be a lot of trees to lock bicycles up at).

Any other ideas on what rivers this could work on?
