Purcellville will celebrate its 75th anniversary as a Loudoun County town with a parade Saturday and with the three-day county trade fair Friday, Saturday and Sunday.

The free Home Improvement-Trade Fair will feature country, gospel, bluegrass and band music, plus homemade food, antique car and farm displays and more than 50 county business exhibits, most of them on home improvement, a spokeswoman for the county Chamber of Commerce said last week.

The fair, also held in Purcellville in 1981, also will feature a National Weather Service exhibit giving hourly forecasts and explaining how weather forecasting is done, new telephone equipment available for the home and exhibits by indoor and outdoor home improvement firms.

The town parade, once a tradition for town carnivals, will be held at 1 p.m. Saturday on Rte. 7 and will feature present and past town officials and Addie Purcell, a direct descendant of the town's founder, Rodney Purcell, who was postmaster and had a store.

Four county high school bands will play Friday afternoon and night and most of the country, bluegrass and gospel music and clogging will be Saturday. The fair is held in the Virginia Skating Rink off Rte. 7. It will be open noon to 9 p.m. Friday, 10 a.m. to 9 p.m. Saturday and noon to 6 p.m. Sunday.
