The rumbling you hear outside over the next few days may not be summer thunderstorms. It could be the 600 Harley owners taking part in "Ridin the Ridge."
Members of the rally were checking in Monday at the Sheraton Hotel off Hershberger Road.
Ridin the Ridge lets bikers explore the Blue Ridge Parkway.
"It just gives people a chance to get together, meet new riders from all over the country," said Alan Fankhauser.
Riders will be traveling in groups and are expected to be in the Roanoke area until Wednesday.
