I'll add my two cents worth. Your listing does us all proud. You have revealed Atlanta to be a big tree city on equal footing with any other eastern metropolis for which we have data. We have so little information for most of the country's large metropolitan areas. Thanks to Steve Galehouse and Rand Brown, Cleveland is on the map. And thanks to the Pennsylvania A-team, Philadelphia is also, and from Darian Copiz's posts and Will Blozan's work, we have some trees in the Washington D.C. area, but we actually haven't even scratched the surface. What lurks in places like, say, Pittsburgh, Baltimore, or Detroit? Who knows? As we know, old estates and urban parks often have trees that dwarf the nth-growth stuff growing out in the surrounding countryside.
For me the downside of tree hunting in urban areas is dealing with the congestion. I salute you and the others who are able to handle the traffic, persevere in finding legal parking, getting permission from owners, and enduring the stares of people who can't image what you're doing with your gadgets. Please keep up the good work.
