Parents, do not forgot that you fill out one item of paperwork to get your base car access so you can just roll onto the campus without having to go through the Gate 1 security building. On I-Day, if you have already submitted it, you will receive a paper pass that is good for the Plebe year, and then you can get the plastic card version later. Do this AFTER the current 1/C graduate! That way, your permanent card will not expire before your kid graduates!
Also, the Mid store will issue you a card that will allow you to shop there any time you visit the campus without your mid present. This can also be picked up during I-Day, or PPW.
(Being local, we actually got both the pass for site access and the Mid store card about two weeks later when there was much less of a crowd).
