I continued my W&OD Trail beer & wine tour with a ride from Falls Church to North Arlington. This route doesn't include any production wineries or breweries, but does include two cool beer bars and a Maryland import, the Heavy Seas Alehouse in Rosslyn. This restaurant serves all the Heavy Seas Brewing Company brews as well as guest taps from Hardywood Park Craft Brewery and Port City Brewing Company among others. To get to the alehouse from the bike path take Nash Street into Rosslyn right at the Marriott. Turn right on Key street, then an immediate left on Oak Street and Heavy Seas is just up the hill. Get used to the hills. The alehouse has a few beers on cask and I enjoyed the Powder Monkey Pale Ale. 
The Lost Dog Cafe maintains a rotating list of excellent craft beer and by setting preferences on their mobile app, you an be alerted when a specific beer or a favorite beer is tapped. Since it's been a while since I sat in the Beer Garden I chose the Westover Market for this trip and at a crowded World Cup watching bar, saw that one of my favorite beers, the Lost Rhino Brewing Co. Zlaty Pils was on tap. This beer was home brewed by a friend and colleague Aaron Hermes, for a Pilsner Urquell homebrew contest. After winning the contest, Lost Rhino offered to brew the recipe commercially. It's fresh, full bodied, slightly hoppy and a solid beer. Cheers and safe travels. Update I: I've been asked to include area bike shops available for emergency repairs. In Falls Church - N Arlington, Tri 360 is on the Trail at Lee Highway. The where Lee Highway intersects the trail again look for Big Wheel Bikes.
