I have walked past this ravine many times over the last few years.  I pass it on my way to get a cup of coffee, usually early in the day.  I have noticed the water and the greens and the roots that are all tangled up.  But recently I saw something else.  And it made me stop and wonder.  Who built this little blue structure?  Has it been there long and I missed it?  It makes me wonder what else I might be missed as I move too quickly from one thing to the next.
