I have a great , cheap solution to make your scrapes work. My father does this.
you find a dry spot on the ground, kick it a bit so that you have a litle area of fresh dirt, you need to make sure you have a licking branch over the spot of dirt on the ground.
then you pee in on the fresh dirt (yes it seems wierd but REALLY works),
find a stick on the ground, scratch the earth with it, make it fly all over the place to spread the smell.
there might be better working systems out there but this one costs zzeeeerrrrooooo dollars.:robot:
