Last year was my first year at indoor worlds. They'll put you through different staging areas where they'll give you the ins & outs then you'll work your way to the practice butts and are aloud as many shots as you can fit into the time frame alotted and then you're put on the line. Make sure you have your water with you and hit the bathrooms before you get in line for the staging area. 40 targets . . . no breaks. Pay particular attention to your numbered targets, as the targets for say the youth will be different white no's on black or black no's on white. Know which are yours. I had a great time last year, have fun, shoot them straight, and good luck.
