Because there is no such thing as too many butterfly pictures, here are some to enjoy! Previous butterfly posts here and here. The butterfly house at the science center is one of our favorite places. Joseph loves carrying around the information chart and identifying the various butterflies we see. Oh wait, there are other things at the science center? We only visit things with wheels, like the Archimedes screw and the expand-able ball at the shop. I've spent three years immersed in the world of little boys, and I still don't understand the fascination with wheels.
