CM escapes her lab early, but I miss one train on the way home and get stuck in local traffic so I'm later than I hoped meeting her at Sligo-Dennis Avenue Park. At a bit before 7pm we trot southward "beside the banks of bounteous Sligo" (to quote Bob Forward's recollection of his middle-school song from the 1960's). The weather is surprisingly cool and dry this evening, and we chat and jog at a comfortable pace all the way to Colesville Rd and back. A medium-sized deer is munching foliage a few feet off the path as a few walkers watch and one takes a cellphone-camera photo of it. When I ask CM to lend me her knife so I can kill the four-legged locust, however, the deer bolts away into the woods.
