The section of the W&OD that transverses Arlington County is fairly well shaded. Because the power line runs right along side the trail, Dominion trims the trees.

Apparently, the power company is upgrading the power lines. The project started last fall, around Columbia Pike. There's been heavy equipment along/on the trail and a lot of mud/muck on the trail from the effort. They are as far as the junction w/the Custis Trail and probably will make it to Falls Church by June.

IIRC, Arlington County has an active "restore the canopy" campaign and will pay folks to plant trees. Not sure of the details but I'm sure there's something about it in the County website. Our yard, unfortunately, has no more room for trees, as we live in an older, established neighborhood with lots of big old oaks.
