Looking sweet, MoonGoat. As to how you said you were going to run the pipe, I kind of have an idea. How about, cut of 2 segments from the back left, and make it either a 4 way or a 3 way junction. If it's 3, have it going up and then come to a 90 degree and head back and over the wall and then 90 degree down disappearing behind the wall and do what you said. Or, you can just do what you said to begin with, so..yeah..I'm gonna go...now...and do...something.

Because I like to blow $%&# up.

Don't fear the night.  Fear what hunts at night.
