We had one road that had been having a lot of new hog tracks on it each morning so thats where we decided to hunt Wednesday night. We decided that we were gonna stay until around 8, which is close to about as dark as it gets at night. It got to be 8 and we hadn't seen anything yet so we decided to pack up and head back to camp. We got out into the intersection of the road and my dad and I both simultaneously spotted a hog feeding on the corn we laid out, and he was coming our way. We slowly snuck back to where we had been previously and got ready. It took him an entire hour before he got to us. I was set up for a shot down a road in front of us, which my dad didn't know. The hog didn't go that way and instead turned around and headed back out into the intersection. My dad said take the shot. I shouldnt have shot cause of the position I was in but i tried it anyhow, I guess it was a good learning experience. My arrow passed right in front of the hog and skipped across the road making sparks the whole way. The hog ran off but I could hear a hissing noise. I whispered to my dad, "I hit one of those gas lines, I hit one of those gas lines!". He couldnt hear it but I knew that was what it was. We packed up and went to the truck and parked it right in front of the hose. There was my arrow dead center in that hose.
