Just a heads up, I'm sure one of the veterans can elaborate on it, but I was told to shoot all 40 targets plan to be on the course the full day. LOTS of people shooting, not like your typical local 3D shoot(although an IBO 30 target course takes us 4-6hrs). Have fun, should be a good time.
You can but it's a beast. I shot 40 targets and the hunter challenge on a Saturday in TN a few years ago. Barely had time to turn in score for the shoot down. If you are going to do it get started as soon as the courses open up.
