CAR, trucks and bikes - the more the merrier for this weekend's Emerald Car Club Op Shop Charity poker run.
"It's all about the atmosphere," club president Leroy Aarts said.
"We have got a lot of support from local businesses in donating goods to be given out as prizes."
There are prizes for the best dressed and, as Leroy explained, the theme is Grandpa Style - outfits sourced from thrift shops.
"Grandpa Style is the dress theme but also how we will drive - no hooning and just enjoy ourselves," he said.
Leroy has his outfit ready for the poker run on Sunday, having shopped at Lifeline and encouraged others to pick up a costume for a bargain.
Everyone is to be at the clubhouse at the Emerald Showgrounds at 9am on Sunday for registrations and the first card.
There is no limit to how many can take part and Leroy encouraged the region's families to join in the fun. Lunch is at Tieri where the second card will be drawn.
"Not only have The Queensland District of the CFMEU, Oaky North and Oaky Creek 1 Lodges pledged a significant donation to the cause, they are also putting on a free lunch for participants as well as anyone who wants to come down for a look," Leroy said.
The fourth card will be drawn in Capella at 1.30pm and the final card at the clubhouse in Emerald where the presentations will wrap up the event.
Cost to play is $10 a hand for those dressed Grandpa Style and $15 a hand for those who don't.
All proceeds and donations will be going to Yumba Bimbi Respite Service.
