When I was a kid back home in Canada, my hunting partner once forgot the key for his gun lock. He came out anyways and tried to scare the snowshoe hares my way
For me, up until this year, I've only forgotten small things like lunch, thermos, water, knife, spare decoy line/weights; nothing I couldn't do without. This year being the first that I've hunted out of a boat with a motor, the number of things I could potentially forget has increased exponentially, and I worry about fogetting something constantly! The worst thus far was forgetting to bring the gasline/hose. Realized it as I pulled into the boat launch... I had my bow with me, so I decided to go deer hunting instead! I'm sure the car parked towing a BBSB looked funny to the other deer hunters in northwest NJ (no water around there for a motorboat for miles)!
