I agree with the shoe print. i used to do tracking, but that was long ago. it would help trackers enormously to have the prints of your shoes.

The scent is very interesting. it seems to me that any article of clothing is good. how about just leaving an old shirt, soiled clothing, in your car b3fore you depart.

trackers will lose much time on stony ground and rock plateaus. if you create some simple rock markers, just three rocks piled on each other, it will speed things up a lot.

The hardest person to track is a small child who is lost. the path is confused and wandering, the footprints are poor quality, and there is no logic to where they are going.
