At the lease,I'm allowed one guest per season...after the three of us who do most of the work at the lease tag a Gobbler, and that's it for that piece of land. One of my best friends from high school came & hunted with a few years ago on opening day because the land owner (who also hunts with us) was at the beach on vacation. We each ended up tagging nice Gobblers & it still ranks as my best day in the turkey woods.
I also have an ace-up-the-sleeve spot I don't hunt much because it is tiny, but when the birds get pressured elsewhere, they usually show up at that spot. I've only had it two years & haven't taken a bird off it yet, but It will only be a matter of time. It is less than 50 acres in size.
Several years ago, I invited a guy I worked with to come deer hunt at some property I had permission to hunt behind my house. Turns out he came back (un-invited on a day when I was off at work) and hunted the adjacent piece of property (which even I did not have permission to hunt). He also parked where he shouldn't have been. Thankfully, he didn't shoot anything, but that was the last time I showed anybody (who I didn't regularly hunt with) one of "my spots".
Now, I have met others at their land and called up birds for them, but I'd never think about going back on my own uninvited. I have also met up with another turkey hunter at a place we scouted together before we hunted it, but it is also not somewhere I hunt regularly. I have enough fun hunting alone or with one of my buddys at the lease, that I haven't recruited many others to go with. The guys at the lease are safe & respectful and take the game seriously.
Luck Counts, good or bad
