At 10,500.... 10mph... 600 = .8 MIL
At Sea Level... 10mph... 600 = 1.3 MIL

I'll be hunting at both, a week apart this year.

Sorry.... that ain't a foot.... it's 11"....

It also ain't 30-40%.... It's 62% more drift at sea level.... again, my bad.

You better pray to the God of Skinny Punks that this wind doesn't pick up......
