You can use the buddy heaters to warm up food.
Horse Prairie campground is a good place to start, you can catch anything from rainbows to browns to ling. Go to where there are lots of huts, obviously that means it's good fishing, but keep in mind that if you fish too close to someones hut, they won't be friendly so keep a respectable distance from them and you'll be fine. Fishing is normally best in the morning! Good luck!
I would just gauge it based off of others around and post up within those peoples distances.
Great idea, but asking someone is ok to drill here goes a long way.
