A little bit of good small-batch Kentucky bourbon each evening, sometimes with filtered water, sometimes straight.  Or perhaps a sip of blackberry brandy.  Or perhaps a bit of each at different times.   ;)

Chocolate.  Spartan1 insisted that there must be a bar of German's Sweet Chocolate as a treat for snack breaks.  We broke off sections as needed.  At home we eat dark chocolate, but the German's seems to travel well, so since that was his tradition back in the 70's, it remained.  I squirreled away a Symphony Bar with toffee chips in the bottom of the food box and that was my special treat for an especially hard day.  Sometimes it  survived the trip and made it home.

Marshmallows.  My husband can toast a marshmallow over an open fire better than any human being I have ever known!

I also clicked "others" and I guess that would include swimming in the lakes in my underwear (because I didn't pack a swimsuit) andn some other activities are too personal to share.
