My wife and I picked up our first tandem this past weekend, a (looks to be) mid '90s Trek T50 hybrid in excellent condition.
Yesterday we did a bit of riding around the neighborhood to get the feel of things. It took us a few attempts to get moving, but once we figured it out we were riding relatively smoothly in short order.
Today we headed out to a local rail-trail. We put in just over 23 miles and seemed to work very well as a team. We both enjoyed it.
