I rode a modest 15 mile ride with a husband and wife team a few weeks back. They were riding linked Ketterweisel delta trikes. It didn't look goofy at all and certainly garnered a lot of attention as we rode. They were having a great time while maneuvering this very long beast through the streets and along the bike paths. The only downside I can see is the cost of buying two very expensive trikes but in this case, you get what you pay for. The ability to split the trikes and carry them individually on and in their SUV was a definite plus.
