espesially during the rut you can try and get on the downwind side of a scrape line... especially if these srapes are on ridge tops or field edges.. sure a buck may walk right up to a scrape but typically only after he has checked it from a distance, ESPECIALLY in heavily hunted areas... they will walk down wind of their scrape line to check them more often than not rather than just walking up to the scrape itself...
find a well traveled trail that runs along with the srape line about 75 to 100 yrds of the line... if you can find a rub line that meets this criteria u r in business... get on the down wind side of tht trail one day on the right wind and if they bucks are cruising you put urself in a good position to make it happen
