I have been into their first 5 albums, well maybe not quite as much into Led Zep III, since I was a teen.  With age I have come to appreciate most of the later stuff. 

I like to learn all that I can about the band's shows in Atlanta and in Georgia as well.  In 1970 they played Macon.  I know that the band stayed  in the downtown Hilton when they played the stadium in 1973 and they stayed in the Peachtree Plaza when they played the Omni in 1977.  If you read Richard Cole's Stairway To Heaven the chapter The Séance is about goings on in Atlanta in 1977.  I have also heard that the crowd at the Omni show in 1977 was more than a little rowdy with more than a few arrests being made.  I have always wondered why they didn't play the Braves Stadium in 1977.  

I was like you originally and I thought the ticket prices were ridiculous.  I decided to bite the bullet and go with people I knew.  Then closer to show time I saw on Channel 11 how the stage was going to look and I thought, "maybe not considering what you get." 

Price wise, it was not a cheap show.  When you consider the stage show and the performance though it was worth it.  GN'R charged a lot of money but at the same time they earned it.  The performance itself was great theatre.  Have you seen any of it on Youtube?  The whole show was shot up to youtube by various people and I have it all. 

I hope I don't annoy you too much when I say I think in time to come that it might be like Led Zeppelin's Mar. 04, 1973, show at the old Braves Stadium and sort of go down as part of 

Atlanta history.

Like you, I say Atlanta instead of Sandy Springs.  I work in Midtown but I wouldn't want to live there.
