#3 on the B-loop was tricky because if you just run to the center of the circle, you'll miss seeing the streamer
Ya, I got so tired of running passed the streamer I found a stick on the ground, weighted one end down with a big rock, and tied the streamer like a banner perpandicular to the cliff.
Needless to say, nobody will run past that streamer again!
Well, they say that a civilization grows great when it's people plants trees in whose shade they will never sit.
All the people that follow will greatly appreciate it :)
