When you all say "buried downspout" exactly how does it get installed (yea, I know, BURIED!).
Does it go into the ground then come out near the street? That's how we did it up north. It went underground right to the curb. Does it just go down a foot then pop back up through a grate? I'm tired of hitting our new gutter downspouts with my mower all the time! Sounds like a simple DIY job.
