If you have a good GPS... you can mark the location of plants that you find while scouting.... and that may just pay off later.
3 or 4 years ago I did some scouting in June... and found several nice ones on some property that I own. I marked the location with my Garmin GPSmap 60CSx...
When I went back the first few days of seng season... we were having an awful drought that year and a lot of the woods greens were dead already... and what seng was there the deer were hitting it extra hard.
I found all of those plants that I marked with my GPS... and most of them had the top eaten and just a stem sticking up.
Not every GPS may be that accurate, but my Garmin put me spot on.
