Stay don't go!

On my way to work today I had a moment of panic when I looked up to the sky and saw grey.... I thought to myself does this means the end is near, is summer beginning to close its doors... but you just came!  I thought it mustn't be but perhaps as the last couple days of August approach why not toast the end of summer with a mint julep. How tasty and easy does this look?  Totally making myself one of these in the next couple days!
