Husband went to Naval boot camp...Some simple questions?

From my experience with the Army, he most likely gets up some time around 0500, lights out is probably around 2130-2200. Letters will be distributed every weekday at mail call, unless something prevents them from being in the bay that day, like a field exercise that extends into the night or multiple days. A letter takes about 3-4 days to reach its destination, so that will tell you when he will get your letter. Assume he will get it about 4 days after you sent it. His first letter will probably say "Hey, I made it to Great Lakes, this is my mailing address, Love you, (Hubby name)" After that, he can choose to write you during his free time. My wife and I exchanged letters daily while in BCT. Don't expect his first letter til the middle to end of next week. If you have more questions, just shoot me an email, and I will be happy to tell you more, but I didn't want to write a small novel here.
