Last year I scraped up a 2 foot area and mixed up 1/2 the concentrate bag and 2 weeks later mixed up the other 1/2 bag. Put it out next to a corn pile. Got several deer visiting on camera and while in the stand. Didn't make a kill. Hadn't been back since season ended, stopped by yesterday...WOW!! It is now a 5 foot circle dug down about 9 inches. Set up another location today, hope to get the same results.
