My nephew Colin has his fundamental origin in pushing his limits to explore the extremes of any situation.  His motto is "Bigger, Faster, Louder, Stronger." A true all American boy so I had to select red white, & blue which also complimented his Super Man t-shirt. I love these photos of him in action; climbing to the top of a hexagonal rope play-set. Aren't the wooden transportation embellishments the cutest thing ever?

Oh boy, I must confess I find it a bit challenging to create little boy themed 
layouts because I can't use my favorite colors or items like flowers and
 butterflies. When I browsed through my wooden shapes, the transportation items caught
 my eye.  I like the look of the natural raw wood so I didn't paint 
them but something was still missing.  Instead I added a pair of Dew 
Drops to each car to create realistic headlights or tail lights.   Dew 
Drops are the perfect finishing touch especially when a rhinestone or glitter is just too feminine.
