Back in 2005, I found an abandoned Bridgestone 300 in Baltimore, outside where I worked (near Camden Yards). I salvaged it and rehabbed it (see photo), converting it into a fixed gear. I've been riding it for the past 4 years now. I commuted on it to work through downtown Baltimore, rode it in a metric century, and have now ridden it in the mountainous terrain of east TN. It's been a great bike. Very solid. It is a bit on the heavy side, due to straight gauge tubing, and came with lower end components. Also, the top tube is a bit short for me, making the bike feel a little cramped. Still, I've really enjoyed riding it and now keep it as a beater.

Also attached is a catalog page for the 1987 Bridgestone 300, which shows what my bike looked like before I had it sandblasted and powdercoated.

Good luck fixing yours up. That's the funnest part.
