Malkin - I so totally agree. My partner and I love riding our tandem together. If we commuted to work on it, we'd just keep pedaling past the office and beyond. We'd quickly be unemployed together!

Becky - Create a saved search on eBay for tandems and be patient. There are often some very good deals on gently used tandems. I'm surprised by how many people invest $5,000 and up on beautiful Santanas, Burleys, Co-motions and the like ... only to have them collect dust in the garage. Eventually they are for sale and you'll get a great bike.

TahoeDirtGirl - There was a feature on NPR about a Buddhist couple that did 100% of everything together, within about 15 feet of each other, for going on 8 years now. The Slate reporter and his wife decided to give it a go for 24 hours. My partner and I were doing the National 24 Hour Challenge bike ride at the time and thought we're doing it one better - we'll never be more than 15 inches apart from each other. Oh, we won the tandem division this year!
