Thank you, thank you Bri!!! Phew... I unzipped my fly the other day and said yes, it was the volcano but it has been so difficult with zoomed pics as they flatten the image out. In some pics it looked 10 feet from the flying exit ramp 74A!
Wow, those two retention ponds to the right have to go soon. They were probably dug as pumped holding pits for any rainwater that would have otherwise filled the area of the mega concrete pour.
