We actually had a lot of fun trying to figure out the wind.
We were shooting off a card table from bipods.....not very steady to begin with. Shooting north, up a slope with what appeared to be a steady north north east wind.
Often three consecutive shots with three different wind holds produced three different dust clouds. We had the best luck just holding a bit high for the first round and making wind adjustments with the next round.
No vegetation to watch sway in the breeze for a make shift wind flag!
