A lot of them know if they have a mailstop date, which is usually like 6 weeks before they actually come home, but we all know the only thing consistent about the military is inconsistency. But yeah, the guys we write to seem to enjoy hearing about the most ridiculous, mundane things. Tell him about Dante and Sandy, or about the weather, or about the ridiculous commercial you just saw on tv. They just like to hear things from home, and to be reminded that *someone* is thinking of them.
