Sorry if this is a repeat, I didn't see anything about it in the first 20 pages.
I know that an ISIC is a good idea, but I'm not a student. I've also heard of an International Youth Travel Card (IYTC), so I was wondering if there is any point to this. Would there be any place I would need to use it where I could not just prove I am eighteen with some other form of ID?
Thanks!
