Prep for distant kids at college

[NorthernRaider]

Has anyone else any experience in preps they made for their kids being away at college or Uni?, When NR junior did his summer camps over the last few years he was only around 2 hours away from home and thanks to the organisations privacy system I had no trouble in hiding some GH essentials and EDC kit in his luggage.

BUT what about when the little buggers are away for months staying on campus or rented dig in some festering slum of a diverse, inclusive, multi cultural crime infested city?

Has anyone else pioneered any useful tips or projects to help our brats survive not only TSHTF but also the day to day risks they face?
