One of my personal priorities for hunting any piece of ground is to know that particular area as well as humanly possible.
One of those pieces of knowledge is to know the prevailing winds there, and how that relates to the thermals and the terrain, under both dry and damp conditions.
A few years ago I started using colored smoke bombs during my off season scouting/bowhike trips. They can teach you a LOT about how the thermals and winds react, and because of the color, you can see it for quite a ways away from where you are.
I have learned to my surprise that on one particular N/S ridge I hunt, that an east wind will for sure blow OVER the ridge top, but if the humidity level is high, then the smoke (and my scent) will SINK about 50 to 60 yards downwind, and then rise UP the ridge side back towards me. This is just one example. I've also been able to determine scent "sinks", in a few areas, due to moist ground.
Has anyone else ever tried the smoke bombs?
