I am not sure of this specific event but, I always bring a little cooler with a sandwich,snack,banana and lots of water. if they have food at the event I will purchase food to support the vendors so they return again .
Good Luck on your first event, Just remember go slow , accuracy is more important then speed, Slow equals smooth and smooth is fast
The years we have gone they served food in the clubhouse. The Sloppy Joe's are outstanding, if a local eatery served it I would order it often. They have long tables and folding chairs so you don't have to eat outside too.
Last two years they sold hot dogs and drinks. If you're there on Saturday when they open, you'll be finished by lunchtime anyway, and they're only minutes from Brighton where there is every fast food and sit down chain dining you could ever want.
