@BumbleBeeBoogie,
Just this past summer when we went camping.
And they were gooooooddddd.
I use the small size hershey dark chocolate - just the right size when you split it half way - once the marshmellow is toasted you have a piece of chocolate on both side of the graham cracker and squish the hot marshie between them - allow it to sit a bit until the chocolate gets all melty.
Then eat.
