The NRA also has a program called NRA U which targets college students and encourages them to become 2nd Amendment activists and supporters. They get all kinds of goodies(T-shirts, coasters, free memberships and pizza). I attended and supported one of these programs on Monday night at GA Tech and we had about 60 attendees.
So any kind of free membership is a good thing to encourage the next generation to become active in preserving and protecting the 2nd Amendment.
