Touring at that time could mean two things: a camping bike, or else simply a recreational bike used for a pleasant Sunday ride to see the sights.
My up the street neighbor when I was a kid actually had this exact same bike. '77 grand touring. I remember oohing and aahing when he got it. The neighborhood wars to see who could ride the furthest and the fastest soon intensified... Before then we were all on huffys, royce unions, all pros, and other junk of that ilk.
