Tom,
Those old pictures are a bit of yin yang. In the old photos, it is much too claustrophobic in #6 for me compared to today's picture, and now that I think of it, 35 years ago it was probably somewhere in between.
On #7, the big difference is the drainage pond that was built somewhere along the way, and to answer Pat's other post, I don't think we should go back to the old look here because I am sure it would be a soupy mess down there without drainage.
