I wish I had the guts to pull the trigger on a good folding bike for touring. I think I'm averse to the idea because the one folder I have is a junky old Tomos 20" single-speed that I bought for $5 at a garage sale. It really rides horribly and I can't imagine taking it around the block, let alone out of state. I know a few people who tour on Bromptons and Dahons, though, and they have almost convinced me that my doubts and fears are misguided.
If I were to buy a folder and ship it over the pond from here in New York, my first ride would be to Liverpool.
