Don I will keep your son in my thoughts.
I agree with Shannon!
I too am a military spouse and depending on his MOS the family may NEVER know where he is or what he is doing! He may be able to contact them yes, but it may just be a "yes I am alive" phone call. Also don't count on those "free" phone calls, or emails. My husband never had access to free phones, nor did he has internet access. It really all depends on their MOS and where they are stationed at! Shoot there were times he didn't have access to toilet paper, much less a computer which had internet. Yes, I sent him BOXES of TP because they had none!
