Good topic, the more I learn about thermals, the harder it is to choose my stand locations. I follow a few general rules with the windand try to stay as clean and scent free as possible. I always hunt the wind but now I watch the thermalsalso[:@]On still days with little or no wind, in the morningthermals move upward asit heats up. In the evening they move downward as it cools off.This is not always the Case, just how its supposed to happen[&:]
