The Friends of Volta Park gathered June 5 at Visitation Prep’s front reception rooms to celebrate and donate to their favorite park in the city. Mayor Muriel Bowser stopped by to compliment the crowd and its 34th Street park. Auctioneer Tom Strike kept things lively and got two persons — Michael Lackey and John Lever — to bid $800 apiece for a singular weekend use of a Tesla, which has a dealership downtown on K Street.
