What did you put in the scrape? The pre/post rut, or the rut? The pre/post shouldn't scare the deer. A scrape is made as a sign of dominance to other bucks in the area during the rut, but during the early/late year, its just a social stop for most deer. It wouldn't scare em if you do it right. Although, if there is ANY human scent in the scrape the gig is up.
