Everytime this thread pops up in "New Posts" I think, "Oh good, the bike has come home!"
I'd like to think that one of Donald's well-meaning friends appropriated the bike to tune it up, and get it all clean and nice for him to use as soon as he recovered. Now the current possessor of the bike is probably filled with remorse because he didn't get it done in time, and he's too embarassed to return it.
