You know, when we were getting you moved in and I saw the top of the carport covered in that debris, I imagined taking an air hose to it. Not sure if that's feasible for you right now, but maybe in the future you can explore the idea for efficiency's sake..
Leaf blower and a rake worked alright the last time. I think this next time it'll work even better if I toss Sam up there and have him do it.
