Trike rental?

[Bruce Johnson]

One of my friends is coming in from Texas to visit the last week of June. A disability has caused him to give up riding standard bicycles, and he now rides a recumbent trike but cannot transport it by air. Do any of you know of a bike store in the Washington area that rents trikes? Or do you know anyone who might be convinced to rent their own trike for a week? 

Thanks!
