I remember the 1965 season pretty well, I was 7, turned 8 around Thanksgiving. Been a diehard ever since. I lived in CO, CA, and TX in the 80s, so I got a little out of touch with the Packers because they mostly sucked and got little air time or ink. I had to rely on the Packer Report for info. Of course, with the internet, I'm as tuned in as someone from Wisconsin might be other than the local, palpable buzz.
I can remember almost all of the players, numbers, and colleges from the 60s, because when you're a kid, that's what you're into. Hell, I remember all of the Bears, Vikes, Lions, Rams, Colts, etc players.
Anybody remember the Packer Press Guide that came out every year? Glossy, about half the size of a sheet of standard printer paper, and had a nice, half-page bio on every player. Filled with history, stats, records, etc.
I think Ford Corp. put it out.
