I have been riding a single for about 20 years. I have always wanted my wife to ride; but, showed interest. To my surprise, she suggested a tandem and I was delighted to hear that. I have read some of Sheldon Brown's remarks on Tandems; but, I would like to hear some suggestions from BF members. Nightmares, mistakes, great days, best advice you can think of. I would really appreciate some insight. By the way, I ride on the average of 4000 miles a year and I know patience ranks way up there.
