We've been riding tandem since 1999 and have about 48K miles together. We didn't discover WS until much later. We've hosted and been hosted. We no longer do tent camping but the last couple of years we've really enjoyed self-supported tours in Canada.. So much more bang for the buck than the organized tours we used to do. Our blog includes a supported cross-US tour in 2012. We've only cycled in Europe once including the Petite Alps in France and a UK Tandem Rally in Edinburgh. Our blog is organized by year but has a good search function. Visit us at https://s2cycle.com. If you also ride a tandem let us know.
