Where in the Sam Hill?

This is Zachary and Sam Hill. Sam Hill was a forward thinking man that made a model road to serve as an example that a road could be built along the Columbia River in Washington that would link Yakima to the Pacific. Little did Sam know that this road would serve the International Gravity Sports and become a Skater and Luge riders dream come true. Sam Hill got his road built and Zachary enjoyed the Competition. Now we know Where in the Sam Hill it all is.
