I had the opportunity to participate in something called the FOD walk at Seatac Airport.
FOD stands for Foreign Object Debris and this is where you walk the runway looking for garbage that can be picked up and sucked into a planes engines.

We got the chance to walk directly on one of the runways because for two hours, planes were not allowed to land on this selected runway.

One of the more unexpected experiences for me were the bugs. There were thousands of butterflies and grasshoppers and in the grass, spiderwebs like this one waiting for a meal.

There were views not normally seen by most people, like this angle at the Airport Office Building from the runway.

There were a lot of dead birds collected as well, this one was lucky and was got 30 minutes prior to this photo. He gets to be released miles away and hopefully will avoid Seatac Airport avoiding getting sucked into a planes engines.
It was a fun experience, I am thinking of making this an annual event.
Last night I had a heck of a time sleeping, I had a headache I think because I was severly dehydrated from yoga. Because I had little sleep, and also I went through this FOD walk, I decided to skip yoga and just hit some pushups and situps.
