How early do you need to get your permit? I attend USNA and won't know until a month or two beforehand what time I get leave this summer. This is something I really want to do and I don't want to miss out on it simply because the Navy doesn't want us to know our schedules too far ahead of time. If it's something that must be done early and I acquire a permit for the time I'll most likely be home, and then end up not having leave during that time, is there any way to give it to somebody else or "return" it so I'm not stealing somebody's opportunity?
Thanks!
