Harper’s Heroes will host their second annual benefit roping for the March of Dimes. The Ultimate Calf Roping will begin Friday morning and will run through Saturday at the Parker Arena. There will also be a free concert Friday night from 6 to 10 p.m. Event coordinator Ashley Lee said they’re going to have two arenas — a covered arena and an outdoor arena –, and the judges will take the average and do a payout winner of each class. Sign ups for the event will begin Friday morning at the arena. Contestants will rope on Friday and Saturday, so they have a chance to participate in both arenas.
