I've done a ton of solo hunts, but that's because I was either stand hunting whitetail, splitting up from a group to cover more area, or western hunts where people couldn't get the time to come along. Success alone is probably higher, but the satisfaction of notching a tag with a capable buddy/family member/child is exponentially better. You share it with another human. It's amazing. My favorite hunts now are the ones where someone else kills the animal. While I'm not done killing animals myself, iIt's far more exhilarating when I'm not the trigger puller.
This year, I was blessed to hunt with my best friends and father for deer and elk and my daughter for antelope. My dad is 74, so our future adventures are numbered, but he's still the best tactician I know. After hundreds of hunts together, I still learn from him each time. We've hunted together for 30+ years, and every hunt is a bonus trip that I'll cherish forever. With my daughter, however, our outdoor journeys are just beginning. I feel the same way about my son who'll soon turn 1. If I'm lucky, I'll get to pass along my knowledge and passion to them.
The torch has been passed, so to speak, and it's now my job to do for others what my father/grandpa/uncles did for me. I gotta say, it's a damn fine badge of honor and one that I wear proudly. Solo hunts are inevitable, and I enjoy them immensely, but there's nothing like taking the right person out and making a memory both parties will remember forever.
