Rocks, Rocks and more ROCKS!

What is it with little boys and rocks? I mean I am finding rocks EVERYWHERE! It is kinda cute, but it is getting a little annoying. Today I found rocks in the fridge, a rock in the pantry, rocks in the washer, a rock in Harper's bed, some in the couch and a handful on the table in Harper's room. This is alot of rocks! And I just threw a couple handfuls back outside just before we left for our trip to Moab. Will this fasination with rocks ever end?
