DS is still waiting here (Florida) as well, both on NROTC and USNA. Nothing to do but wait and work on plans C, D, and E just in case. We're all anxious to see something, and he would like some idea where he'll be moving this summer. He's wanted to serve as an officer since elementary school, so he's very nervous that he hasn't heard anything yet, and it's hard as parents to sit by and watch him wait. Not to mention the inconvenience for us, as a lot of decisions are going to have to be made in a very short amount of time, from what bank we should set up his checking account (are there branches/ATM's near whatever campus he'll be at) to what days I need to take off this summer to get him where he's going, and are we driving there or flying there... and to whom should we send deposits.
However, I try to look at it like potty-training when they were toddlers. At the time it's one of the most important things going on with your child, but when it's all done, you barely remember the time and effort that went into worrying about it. There will be other things to worry about after all decisions have been made and everyone is settled in to where they're going.
