You will not have to worry about where to park. There will be plenty of signs, cones and guards directing traffic. Have your cell phone with you -- so that you and your basic can connect (most, if not all basics, will be given their phones so that they can connect with their parents at A Day). Know what squadron your cadet is in (academic year squadron). The suqadrons line up left to right (as you look at the field) (#1 and 2 on the far left of the field, #39 and 40 on the far right -- as you look at the field from the bleachers)
You will have time to run on the field after the parade and find your cadet. It seems over whelming at this point but it will work out and you will find your cadet. If you need a back up, say that you will meet on the steps of the fied house -- you will find each other.
