MJR, I have a mock scrape going right now with the dripper bag also. I'm using Hawg's Buck Fever line and it worked well to help me bag my first buck this season. He caught the scent and walked straight to the scrape and starting sniffing all around it and rubbing his head in the branches above. I'm keeping that scrape active and have seen some doe prints in it, but no real digging like the bucks do, yet. I'm not using anything that resembles the rut yet, since it is still 3 weeks away here in Nebraska also. I'm using Hawg's BF Pre and Post Rut scent on the ground and in the dripper and have sprayed BF Gland scent in the branches above the scrape. From what I have read, this is the most important aspect of mock scrapes- spraying some sort of gland scent on the branches above. It worked for me. The buck I got spent several seconds sniffing and rubbing his head in the branches I sprayed the gland scent on.

Hope this helps out some,
