Schwinn Free Spirit? Sounds more like a Sears Free Spirit. I have seen other C/L conveniently mix up brands to mask the "true" identity.
I have a Woodlands myself, picked up at a garage sale for $5. Not sure what I am going to do with it. Its a decent basic MTB. I think it has a cromoly main frame. It would make a good grocery getter IMHO. Put some 1.5 inch wide city tires on it, and you would be ready to go.
I would be very suspicious on that Schwinn Free Spirit. The Sears bike was a real POS.
