ANTIQUE CARRIAGE SHOW

More than 30 classic road coaches and park drags, with whips (drivers), groomsmen and ladies and gentlemen dressed to the nines, will be on parade at the Upperville Horse & Colt showgrounds from 10 to 11 a.m. Saturday. Organizers say it will be the largest collection of the coaches -- many of which are from museum displays in Europe -- ever assembled in the United States. The event is a fundraiser for the National Sporting Library in Middleburg, which is celebrating its 50th anniversary. Route 50, one mile east of Upperville on the south side. $10 a car. 540-687-6542.
