Was just wondering, when did the door operators stop opening the doors just a little bit, to let Bob walk through rather than now, where it just looks like they tug on the ropes and let the doors fly out. Everyone must know what im talking about, and it was done for many years, 70s and 80s, and early 90s, only the first 2 panes or so moved and all the other panes stayed the same, and the door closed very slowly as he walked out. i know that probably took more time consuming stuff, but i certainly liked it.
