Close to 200 bikers from across the region and beyond will be in Hanover this afternoon and evening.
It's all part of the 5th annual 250 kilometre Biker Poker Run.
Proceeds from the event will be split between the Grey Bruce Society for Autism and the Goderich Tornado Relief Fund.
Organizer Anita Maahs says bikers make great fundraisers because they love to ride and they are always eager to support a worthy cause.
The poker run stretches across the region and ends at the Queen's Push Pub in Hanover.
A party will follow -- complete with a large outdoor tent and live musical entertainment by Dirty Mac.
But you don't have to be a motorcyclists to join in the fun -- Maahs invites everyone to come out and join in the party after the event.
There will be a pig roast (15 dollars a plate), an auction and as mentioned live musical entertainment.
The poker run usually raises anywhere between four and nine thousand dollars a year.
