^second. Don't use the number holders, they glare. If you YouTube hunter hair there's a good cronofhorse video on getting your hair up. I have long hair, and get it put up in my hat no problem.
For highlighter, baby oil will do. No need to spend $10 on a jar of the same thing :)
The best thing you can do to catch the judges eye is sit up, be confident, and have fun showing off what you've got! Huntseaters show off the rail to be seen. Be courteous and make sure you're not on the judges and that others can still navigate/pass you too.
