JohnP: I've been calling several areas around the Bradshaws. It took awhile to find good sign, but, there are two that have multiple cat sign. My problem is timing my calls to the approximate time that those cats may be back in the area. It seems to be a pair and they seem to be coming across this one saddle every five to six days.
I've been scouting in proximity to 5B in one canyon that takes about a hour and half to access from the last of the road. Good sign there, too.
In SE AZ around the Chiracahuas I found two fresh deer kills that were definitely visited by or caused by lion, but, on a subsequent visit I found no fresh sign.
And, thanks for your offer. It is always interesting to get out with experienced callers and hunters. For the balance of Spring and during Summer, my orientation will be up on the Rim; around Fall I will start calling the southern part of the state.
Others: thanks for your comments and stories. I've only killed on mountain lion from a call stand in four decades of calling. The suggestions here that stands for lion need to be longer agree with what others have suggested. Two area callers that have had some notable success stay on stand for at least three hours! Now, that's discipline!!
One of my biggest challenges, after two long, long stands, is passing on curious coyotes. A ghillie suit certainly has proven its worth in concealment and tends to minimize the motion of needed shifts in position on these long stands. Effectively, I am limited to one stand per day given travel time, etc. Falling asleep during the predawn while on stand is another challenge; if you hear of someone getting eaten or mauled while calling, it could be me. Oh well.
Now, I just need to get the big kitty before the tag in my wallet wears out. Like the condoms of yesteryear.
