Lets see if I can actually remember this...
1994 Barracuda A2E - 1 month - 0 miles - This will be my winter bike, and a nice comfy bike to ride the rest of the year. It's got a front disc, and a rear Nexus 8 speed hub with coaster brake. Still trying to get everything together for it, I wonder if I will ever figure out what size seatpost it needs, and then if I will ever find one that size...

1988 Centurion Ironman Expert - 2 months - 70 miles - Rode it some as is, broke a spoke (Hint, leaving a bike like this sitting around at work is a bad idea) and now I'm waiting till I have all the parts to swap to 8 or 9 speed.

1970's Raleigh Record - 3 Months - 10 Miles - Started as a fixed gear conversion in poor shape. First I got a crankset and new front wheel, rode it a bit, and now I'm converting it to a 3-speed. Fixed gear was fun, but now I'm having back problems, and this should be a nice comfy bike to ride around till the Barracuda is complete. Once the Barracuda is done, I'll probably strip it down and give it the paint job it badly needs.

1982 Motobecane Mirage Sport - 3 months - 250 miles? - Bought it with plans to be a commuter, and still haven't got all the stuff I need for that, or decided if it is even the bike I want to use for that. But the GT and Centurion both developed issues within a week of each other, and this is what I'm riding most right now.

1995 GT Pantera - 1 year - 1500-2000 miles? - I slowly turned it into a pretty fast hybrid, and was my main bike for quite awhile. I've decided that I'd rather have a fast road bike, and a more comfy bike instead of it though, and the front cantis decided to fail when I was towing home the Barracuda. I guess it knew that it was going to be replaced.

There probably was a few between the GT and Motobecane, but it didn't take long to decide they weren't keepers.
