The roller derby league host and coordinate the events I list below. It is the skaters/refs that are wearing a league jersey, do the judging, present the awards, and benefit from your support. Visiting their merchandise table and getting a memento wouldn't be a bad idea either. Sometimes they offer discounted tickets to the next bout.
Coordinate with a local county park for space. All competitors get a 10 x 10 area to set up a table and have electric outlets to prepare their chili. They pay a $20-$30 entrance fee and must give samples to all participants (especially the judges). Spectators are only charged $1-$5 admission to walk around and sample all of the chili available. The winner is awarded a $50-$100 gift card, recognition in the league program, and season tickets to all roller derby bouts. I recently placed 5th of 80 entries in one.
Same info as the chili cook-off, but is about ribs or burgers instead of chili. BYOG (Bring Your Own Grill).
Hot Dog Eating
Coordinate with a place to host the competition. Find a local hot dog restaurant to help sponsor it (they might sponsor the league too). Competitors pay $5-$10 to enter the contest and have to eat as many hot dogs in one minute as possible. Winner gets a T-shirt, recognition in the next bout program, and 2 complimentary tickets. Our last local winner ate 31 hot dogs in 1 minute.
Pie Eating Contest
Similar to hot dog eating one, but is about pies instead of weiners.
People pay an admission (under$5) or make a donation, and the skaters wash their pets (dogs, cats, hedgehog, etc).
Children under the age of 12 participate. They donate $1 per entry and get to color (with Crayons or markers) a picture with the most inspired theme that they can dream. The winner gets their image scanned, posted on the league website, 3 complimentary tickets to the next bout, and recognition at half-time.
That is all I'm going to say for now. I have more events that I could share but I don't want you to scroll down too much. Bottom line, support your local roller derby league.
