I usually fish big rivers and stay in a near by hotel. I carry 2-3 bottles of water, bags of nuts, beef jerky and maybe something a lil sweet. The truck is usually within an hours walk back, in it I keep an ice chest of water, soda, and beer. A thermos of Hot coffee in the winter, none in the summer. I may take sandwiches and chips (crisps) if I don't want to get off the river. Other wise I (we) drive back to the hotel for a meal and rest/relax then back out on the river till dark. The grills and adult beverages come out for supper, or we go to a local restaurant.
Longer camping trips with the fishing club (30 to 125 people use tents, trailers, back of trucks and hotels) require a daily happy hour at 5 with wine & hors d'oeuvres usually cooked by the wives & girl friends, followed by a late supper. Supper is usually on the grills or in Dutch Ovens, no one goes hungry. A "pot luck" always happens on one of the afternoons as an early supper. This is a 300+ member (families) fishing club that enjoys eating and drinking as much as fishing. All the grandparents get together to show pictures of the family and tell stories and play cards & board games.

Others are knocking back the cocktails.

More of a outdoor social club than anything, good folks and lots of fun.
