I've said it before, here recently, you guys don't know how lucky you are to have the availability and choice of quality tandems you've got AND the tandem rallies you can ride in, I'm truly envious.
The city where I live in Oz has a population of 100,000, the cycling community is very strong and has produced Olympic and World Champs, but tandems are few and far between, however of late we're tried to organize some tandem rides and there's an enthusiastic core who are hoping it catches on...wish us luck.
