I'm not sure if there is such a specific 'bailey pickett lemon tits fanfic' available. It could be a very niche or even an unknown creation. You might try searching in some very specialized fanfic communities or websites, but keep in mind that it may not exist at all.
Since I'm not sure if this fanfic actually exists, it's hard to say for sure. But if it did, perhaps it could be about Bailey Pickett having some sort of adventure related to an object or character named 'lemon tits'. Maybe 'lemon tits' is a code name for something mysterious, and Bailey has to figure it out.
In my opinion, 'Open Season' is one of the best Joe Pickett novels. It sets the stage well for the character, introducing us to his world as a game warden in Wyoming. The mystery in it is engaging and it gives a great sense of the Wyoming wilderness that is so central to the series.
The latest Joe Pickett novel is 'Treasure State'. In this novel, Joe is once again in the middle of a complex web of events. His knowledge of the land and his determination to do what's right are put to the test. It has elements of mystery, action, and the exploration of the human - nature relationship that are characteristic of the series.
