RE: Mock scrapes/scrape drippers
Most drippers are designed to drip durring daylight only. How they work is when it's cold (at night) the fluid contracts and is drawn back into the dripper. as the sun comes up and the dripper warms up the liquid it expands and starts dripping until the temps cool and the cycle starts all over again.
Mock scrapes can be an effective way to hunt but you must take every percaution to be scent free when setting them up. If you leave human scent in the area the gig is up and a mature animal will stay away. I started some scrapes back early in the year and they have been active sine april. I've steered clear of them in the past couple of months to allow the animal to do their thin undisturbed. When the rut picks up I'm planning to hunt over them with my climber. Only time will tell just how effective they are.
****If your making mock scrapes don't forget the licking branch. this may be even more important then the scrape itself.****
