mmm, fresh snow..we got some of that in Ottawa last night....

That's a nice lugged steel mountain bike you got there! If it's your size and you hope to use it I suggest you strip the frame of all parts (hopefully nothing is siezed up) and replace what's needed as it looks to have been neglected for a while. I suspect it's a mid level model from the mid 1980's, based on it being lugged and using 6 speed thumb shifters.
