Not sure if it counts, but I have my Schwinn Hurricane (1993-ish) sitting in the garage, unused for now. I put a few miles on it back in the day but I don't think I was ever as comfortable on it as I am on the Specialized that is my main bike for now. I've debated upgrading a couple of things and using it around here as an errand/commuter bike next spring but to be honest, our roads (and drivers) here are very bike-hostile and I tend to take the car instead. IMHO it is not as refined as more modern bikes are.
Never considered taking it out on the trail, especially since I feel that the frame is a little too large. (I wish I had gone a size smaller--the LBS seemed to think it was a good fit for street use.) And I'm not certain how good the components are (Shimano GS70 for derailleurs, I think, no clue on the rest).
