I am just as happy about it as Peach is; and no, she didn't tell me anything. I figured it was a strong possibility once we had tweets from Atlanta Airport and Facebook.
Swan House by the way, is in the middle of the Buckhead neighborhood -- very near -- three or four blocks, depending on how you count them, of the main intersection of Peachtree Road and West Paces Ferry, and directly off of Andrews Road. (There's a Swan Coach House restaurant, that is on the same 30 or so acres. but it is not the Swan House.) When you look at the neighborhood on Google Earth, you will understand why Peach and I both say it is hard to get to even for the taxi drivers; and it is in the middle of a rich, urban neighborhood!
Edited to add: This is the second finish line in a row that I have been to (more than once each, oddly enough). That is just weird inasmuch as I've never been west of the Rockies.
