I like the idea of a Pie Run, and this could open the door for "Themed" rides.
In SA we have a ride, commonly referred to as the "Six Ferries Ride", whereby we can cross the River Murray six times by ferry in roughly a 450km day ride. The route looks something like the attached, but Google Maps has failed to cross the river at at all the ferries. The route goes from Adelaide, and crosswes the Murray at Wellington, Tailem Bend, Mannum, Purnong, Walkers Flat and Swan Reach.
