The 123rd annual Daddy of 'em All unofficially gets underway Sunday with a cattle drive.

Cheyenne Frontier Days will drive nearly 550 Corriente steers more than four miles from their pasture north of Cheyenne to Frontier Park.

The drive begins at 7:15 a.m. at the intersection of Hynds Boulevard and Horse Creek Road.  It then heads south on Hynds to Central Avenue, before turning onto Kennedy Road and Carey Avenue.

CFD officials are reminding spectators not to park along Interstate 25.  Motorists should also be advised that Central between Hynds and Kennedy will be closed while the cattle are on Central.
