RE: coffee
I guess I'm one of the few who doesn't take refreshments.
I took a couple of sandwiches and a bottled water for my only all-day sit, last year. Other than that.....I think I took a power bar maybe twice. I'm only out there for no more than 6 hours at a time.....and I'm good for that amount of time.
Never taken anything to eat/drinkfor a morning sit.....even in 14 degree weather. I just don't like the extra weight.
