It's called the Carnival for Troops because a portion of the proceeds go to supporting the nonprofit Guardians of Freedom Project. The charity tells us they get a portion of ticket sales only, which has amounted to roughly $1,000 to $2,000 each year.
Donations are also accepted on-site, and T-shirts are sold to help wounded warriors.
Each ride costs $3.75, or you can ride all day for $25. There is a discount for military members.
