Three Seasons

My cousin's name is Summer, not too long ago her brother married a girl named Spring. Well, while we were all together in Nebraska we took a picture of the "Three Petersen Seasons" (even though one is now a Zerr and one is a Triebenbach). And we added my Aunt June in the second picture. Summer's middle name covers the winter season so now we're all set. (Summer is on the right and Spring is on the left as you look at the picture). I also have a cousin named April, is anyone else noticing a theme here?

Here is the one with Aunt June added. Aren't they a beautiful lot?
