I hunt alone the great majority of the time. But, now that Dad is actually gone, I won't be able to call and invite him-the past several seasons, I knew the answer would be "no", when I asked, but, I called anyway. I would tell my Dad where I was (he knew the haunts as well as I did) and let my wife know if I wasn't home by such and such a time, to call Dad.
Dad always called in the evening to see how I did.
Best,
Ted
