Card Shop in a Tree

 The boys have been hard at work creating a trading card shop in Calvin's tree house.  One day I got a bunch of pictures from my neighbor telling me how they were sprucing the place up in preparation for the grand opening.  The boys are always busy being creative and adventurous together.  They brainstormed all their pricing, hours of operation, marketing, and who was responsible for working.  Their plan is to be open on Halloween where they will have their biggest sales yet :)
