If the National Christmas Tree Lighting is my version of holiday hell (nothing says “Christmas cheer” like a competitive ticket lottery and Fall Out Boy!) then the Scottish Christmas Walk Parade in Old Town Alexandria must be heaven—where “Scotland the Brave” is always playing and Scottish terriers are wearing sweaters. The parade, now in its 45th year, features clans displaying their tartans and crests, Darth Vader in a kilt, pups wearing plaid, and bagpipers playing in the streets and town square. It’s part of a three-day celebration of all things Scottish, which kicks off Friday with the Heather and Greens Sale and Taste of Scotland; continues Saturday with the parade, house tours, and Holiday Marketplace; and ends Sunday with the kid-friendly Deck the Halls events featuring Santa. The parade has all the small-town charm of a snow globe scene in a Metro-accessible setting. Did I mention there will be dogs in sweaters? The parade begins at 11 a.m. at St. Asaph and Wolfe streets, Alexandria. Free. (703) 549-0111.campagnacenter.org/scottishwalkweekend.
