That is awesome!!! Makes you feel good to know that they'll call em all over...
As for first husband and wife to kill them in the same year, I doubt that. I know 3 couples personally that have world slams.
BUT I do know the year prior to the world that two of those 3 couples killed a grand slam in one year.
That's neither here nor there, that is awesome! I hope they send you some good pics with your calls in it.
My wife and myself plan on a slam this year toting a couple of guys on here's calls.
