In my expirience hunting scrape lines can be very rewarding during a small window each season. Theres few days where the bucks are raring to go and the does still haven't got to that point yet. The bucks seem to visit their scrapes a little more often and can be patterned for a very brief time. This is when my journal comes in handy, I've found that there are a few of the same scrapes that annually get visited by numerous bucks during this time period. Only because of bad stand placement and poor shooting (buck fever), I have failed to cash in.
