Sorry to here about them not getting back to you. Somebody should have gotten back with you. We are pretty busy but still its your Tax Dollars. Id give them another call and tell them you want to tour the station.
I guess the one piece of advice to give is make sure you tell someone reliable were you guys are going to dive and what time they should expect you back. This gives the search team a huge heads up when the time comes to look for you. The reason being say you and your wife go out diving and just tell some people your going diving. Well when no one heres from you and the CG gets the call. The people in the ops center have to do there home work on when you should have gotten back could you have stopped off some were. Then After that is all done they need to find out were you were supposed to dive. Then they get the area then they need to get the local police to see if you car is there. If it is then they need to get permission to launch a boat, a helo or what ever they deem necessary.
Now if you do it the correct way. You guys miss your deadline. Your reliable source says. Hey there not back they were supposed to be back at ??:?? this is were they dove. Now the ball is rolling alot faster they know all the facts right away and gets everything going faster. I hope this helps. Go take that tour.
