Looking back every year.

So far, we have taken a picture every year we have been married. I thought it would be a fun thing to frame in one of those larger multi-picture frames and show the number for every year we have been married and see how we change & how the family someday grows. We don't always do it on our anniversary, but sometime during the summer we try to get someone to take a picture for us.

We end up with some pretty hilarious outtake versions every year. Who knows how hilarious they will be once you throw in future family members right? Like a puppy maybe?
How do you guys document your anniversaries? Do you do anything similar or are we the only strange ones?
