Let's.

You and me.  Let's go climb a mountain.  Let's go play in a freezing cold stream with mossy rocks on the bottom on a hot summer's day.  Let's explore a city with artists and lovers and sky scrapers and geese.  Let's find an old village in a distant country and commune with the people.  Let's walk through tall grass.  Let's feel the air and hear the ocean's voice. Let's go!
