Find a tree with a branch low enough that a deer could reach it. Without and "licking" branch (I think that's what they're called, but my brain isn't working a whole lot right now, I'm tired) the deer will know it's not real. I'd suggest buying a scrape dripper because it'll keep deer coming in and you don't have to be out there.

I think they'll work better if they're placed on an already made scrape line.

Just get a stick and clear out a spot in the leaves maybe 2x3 feet or something like that...you might take rubber gloves or disgard the stick somewhere else when you're done so that you don't leave human scent mixed in with the deer scent.

Minus the scrape dripper and the scent...if you just make a mock scrape and then pee in it yourself, it might work. I've heard of it working for guys before.
