It was grey here too, but at least it's green and we sat outside for dinner. So, this was my first time through an airport. I breezed through, no problem, but I did learn something. Our airport has both the standard metal detector that you walk through, and also the full body scanner that you stand in for 3 seconds. I was in line for the latter, but then stepped over to tell a security guy that I have knee replacements, thinking that if they have to call someone over, I might as well not wait in line before telling them. But he said that I was in the right line, that the scanner was the machine I wanted to go through. I didn't need any further inspection. Had I gone through the metal detector, I would have been pulled aside. So, if your airport has a scanner, get in that line!
My knees do feel swollen tonight after flying. I think I'll muster up an ice bag before bed. But it didn't keep me from taking a nice walk after dinner!
