Make yourself a cow (cattle) decoy or a elk decoy (cow). They are used to seeing these animals in the trees, the elk, especially in the "DG's".
Don't just rely on a regular goat decoy, as they might not come to that if they are not in the rut.
Goats are very territorial and don't like trespassers. Rely on another decoy to get closer would be better.
Make sure the decoy you make has a place to hang your bow and a window that opens where you can shoot through the decoy.
Having both would suffice in all situations. If you find a big goat, try increasing the horn length of the decoy and they will sometimes come a running. Usually the length of the original decoys horn is too short. Another decoy - a doe with the buck works great too!
Good luck.
