In 89 my I took my oldest son Kirk on his first camping and fishing trip. Kirk lived with his Mom and stepdad. They had never taken him into the outdoors or done anything with him to prepare him to live in the outdoors. I was being very patient and teaching him things as we were going along, trying to stay ahead of him so he would not get hurt, or do something dangerous. We camped on the banks of the Deshka river, and had caught and released several Kings. As evening approached I fixed dinner at the camp fire. I heated the canned goods by placing them near the fire. The thing that Kirk missed was my punching a hole in the top of each can. After eating we went back down to do some more fishing along the river. After a short time Kirk informed me he was hungry again, he asked if he could go back and get something to eat. I told him sure go ahead, thinking he would hit the cookies, or pudding cups. Right after he went back up the bank, I hooked a big King. Kirk came down and helped me to land it. After that I decided it was time to quite and return to camp. As we approached the camp Kirk suddenly said "Oh I forgot my can". I looked at him not comprehending what he was talking about. Then I heard a muffled boom and looked toward the sound. I was immediately hit by many flying projectiles, that left a burning residue behind. I got hit all over my body but my unprotected face got the worst of it. I yelled mainly from surprise, and started wiping the hot residue off. Kirk seen me wiping my hand across my face and smearing red stuff all over my face. Kirk thought I had been seriously hurt. The kid went into panic, he thought he was responsiable for my getting hurt. I ran back down to the river to wash my face. Kirk ran along beside upset, asking me if I was going to be alright. After washing Kirk discovered that it was only the tomato sauce making my face red. Then he told me about setting a can of pork and beans next to the fire. Since he was in a hurry he decided to just set it in the fire to speed things up a bit. When I hooked the fish he forgot about his cooking and came down to help with the fish. Kirk remembered just as the end blew out of the can, and I got sprayed. It made a perfect cannon.
