Though I fly through the valley of death, I shall fear no evil. For I am 80,000 feet and climbing.

The Road goes ever on and on
Down from the door where it began.
Now far ahead the Road has gone,
And I must follow, if I can,
Pursuing it with eager feet,
Until it joins some larger way
Where many paths and errands meet.
And whither then? I cannot say.
-J.R.R. Tolkien

KTH takes security seriously. Saw this guy guarding the forest facing entrance.
