The ride starts at 5:30pm with thousands of bikers participating.
It's the Thunder on the Isle -- The Mayor's Ride, which revved up for the first time eight years ago.
The riders take off from Harley Davidson in Millcreek and head down to Presque Isle for a beautiful ride.
The Mayor is a strong supporter of the roar, and so are visitors who appreciate that the Mayor has a motorcycle.
Bikers pitch in $10 for the ride which will go to the Saint Patrick's Haven this year.
