i am currently in CT though my experience extends to my youth where i was raised in west Texas. i used to find hogs in my back yard there. The lizards and toads that the hognoses fed on in that area were then used for scenting and i came to my stated conclusions. Here it is also harder to get lizards native to areas where Heterodon nasicus live. i have tried anoles as well and they have proved ineffective time after time for me. So toads are simply the more effective and accessible source of scent for me.
