Was trying to remember if USNA did a color vision test and eye exam, but I can't remember! I seem to remember there was. Will have to reach out to the current Mids I know. As 08 said, I Day hasn't changed much in decades. It is a well oiled machine. To be honest most Plebes won't remember much of it. You just get in line with your check list and follow the herd. And for crying out loud when someone asks what size you are please do not respond with 'I don't know, I have to ask my mom!' I have heard this a million times on I Day.
08, I was at the dry cleaners the other day and I still use my original laundry bag (the one we got in Alumni on I Day... I can identify this one because of course my writing is so slanted and barely fits on the bag in my haste) and a grad walked in behind me the other day and couldn't stop laughing at me! I can still vividly remember writing my name, alpha (which I couldn't remember, company/platoon on there. Hey the bag still works well!
