A hole to see in a pipe

Sometimes, things are done in a strange way.  It makes me wonder the why things are made that way.  The above picture is the perfect representation.  In this case, we can wonder why a hole had been made in the pipe.  I am sure it is more than look into the pipe.  If the pipe had been longer, I would have guessed it was for rainwater or something like that.  I haven't took a photo to show the lenght of the pipe but it isn't a very long pipe.

This place is a bit remote.  There isn't any crowd to take a look inside the pipe, just for the fun of it.  If there was fishes passing in there would be a real treat!  The main problem I see is the automn leaves going into the pipe throught this very hole.  Not very practical  I don't see the use of the pipe either.  Erosion will take it's toll on the surrounding, pipe or no pipe.  I would like to see the logic amd I may be very ignorant.  I guess a pannel explaining this would be needed for people like me.

I think it is a recent addition to the place.  Already there seems to be rust.  The sign is visible with the green on the tubing that permit us to see inside.  I am sure it will not last long.  Not a decade for sure!  Maybe the people who put it there were for a quick fix without any long term intention.  Personally, when I do something, I like to be a lasting object.  The more lasting, the better.

I think I will stick with admiring the nice peobles arount that pipe.
