Went by our (usually closed) co-op to check on the dumpster this week and found this tall Backroads MTB from the '80s hanging out by the dumpster. I don't mind dumpster diving but this technically wasn't in the thing so I left it alone but posted about it. Another forumista inquired about getting it so I phoned the co-op and was told that stuff around and in the dumpster is fair game so I grabbed it. Originally sold by The Unicycle in Blacksburg VA the serial number looks like it has a misstrike.
First character looks like a bad 6 (Maybe a C?) followed by 690003. Hope this helps.
