A small neighborhood park tucked away from the major roads with lots of tall trees. You might spot a deer or two during your visit.

A monument to invasive weeds. The entirety of the park is like a most noxious list of invasive weeds, totally overgrowing the strip of park along the suburban roads and the stub end (playground area) of it: Porcelainberry (it should be renamed “Porcelainberry Park”), Bamboo in the stub end, English Ivy, of course – through in noxiously comparison with the earlier two, ivy seems quaint. The kicker: Fairfax Parks doesn’t care, the park is entirely overgrown with ugly vines and bamboo, except for the mowed patches. If this was rich McLean, there would be remediation attempts, but until recently this has been a working class neighborhood, and no one cares. There is nothing notably nice about John Mastenbrook-Greenway Downs Park except it has a standard basketball court and a playground. Otherwise, it’s an eyesore.

Nice to stop for lunch sometimes, when not busy, and have the place mostly to myself, but dog walkers going by. Mostly friendly but one dog doesn’t like me at all, and is scary,needs to be controlled… Park hours depend on sun 🌞 Rise and Set times which gDrug gMaps doesn’t handle relative times well/at all…

Cozy little Park with a loop through the woods and a small playground. Little sanity for someone who grew up out in the woods. Mosquitos are rampant much of the summer
