The left of the two gates immediately behind the escalators up from the train (yes, north satellite). Especially fun when you use a cane and already came in from the light rail! (To be fair, my timing was perfect and I got the shuttle cart from the light rail to the terminal, but it's still a bit of a hike after that. The bigger problem was returning that evening on QX, hiking in from C2 about 2300 after a delayed flight, then there being absolutely no sign of that cart which supposedly runs continuously 0500-2400. I was dead by the time I got back to my car at Angle Lake!)

To hijack the thread momentarily: kudos to TSA at SEA for letting me use the priority line (I still had to go through normal screening, but didn't have to stand the paltry 5 minutes in line) and to the QX staff at GEG who gave me a pre-Check card -- I think that was partly due to the cane and partly due to my pointing out to them that the flight was delayed (the delay was posted while I was in the process of checking in -- it was on time when I started, and 50 minutes late by the time the BP printed). Completely unnecessary on both ends, but I appreciate the thought!
