Don't give up, it'll happen.
If you find enjoyment in the outdoors then just have fun trying.
It is possible to hunt without calling. Set up on one of those trails with the wind in your favor and wait.
Also as an experiment, I put out some spoiled chicken and they came.
My camera shows them coming back to check and I've only done it once.
I am still learning all about coyotes that I can.....we will all learn together here.
