now that sounds interesting. never really thought about it, but a U shape and some 2" pvc pipe. and little bit of tape. awwwwwe. i see the possibilities. even blowing out the down spots.
though wonder how well it works, when gutters are plugged and water standing in the gutters, and getting mud and like all over the place including yourself.
maybe an additional 90. so it blows air down the length of gutter. vs straight down into the gutter.
