Good luck with recruitment!
I already know what school your at (which you said people would probably figure out), so I would suggest making very non-specific comments. For example, I wouldn't say "so I decided to wear jeans and a pink top with flowers and sandals and my blonde hair was in a ponytail" or "so I went to ABC and they wore a blue top with white bottoms and I really didn't like them". These are just examples, but the more specific the comments the easier it is for people to pick you out.
I am pretty sure a few GC members go to this school.
Have a wonderful time! Keep an open mind!
