electric pole-saw

I got out and used the pole-saw to clear out some dead wood, and to trim the mimosa, etc....I got about 3/4 finished with what I'd been thinking of doing and my back was starting to ache, so I knocked off for the day....experience has shown me that if I keep going too long after the ache starts, I might not be able to walk the next morning....have to crawl out of bed.....anyway, it was a good morning for yard work, 59 and overcast, got sweaty but not overheated, you know what I mean.....so now there is a pile of sticks and branches out at the curb for Tuesday, when the City truck comes around for that kind of thing......
