I have found rubs like those from deer as well as moose up here.. I once used a whole bottle of Indian Brand Buck Lure to try and get a big buck out. It was a long time ago and that buck came out at night and made a whole new rub. It was unbelievable the size of that rub. So I guess, all I did, was make him mad as he swam across a river right after making the rub.. I never could catch up to him in the day light hours tho...
