From what I have seen so far, I think this rig must surely take the cake. I recently turned 18, and it seemed obvious to run a ride to celebrate. These photos was taken in Maryborough, in Victoria (Australia, for those who don't already know). The BOB trailer is actually not mine, but I have the couplings on my bike as I use one occasionally to take books to school.

I am a member of a bicycle touring club in Melbourne, so getting together a reasonable sized group was quite easy (11 in total). We caught the train out to Bendigo and spent three days cycling around central Victoria, and finished in Castlemaine.

For those that are interested, no, I don't own a car. I am not a car hater, but I have found that a bike is more convenient, and a lot less expensive.
