I couldn't think of any hunting superstitions affecting me until I saw Dwayne's picture with the coyote.
White-line spacers. (UGH).
I don't know if it is a superstition or a rule, but please don't make me hunt with a gun with white-line spacers. Sure to be bad luck in the making. LOL.
I have removed a few white-line spacers from otherwise good guns in my day. Sort of akin to an exorcism, I think.
