All the scent free soaps, deoderants.........Rubber boots, Scent Killer Autumn Formula spray,Red Fox Urine.

Stay off the trails as much as possible, use the wind and cross my fingers.

I do wish I could find my "Old Gray" Gray squirrel cover scent spray. ManI liked that stuff. I don't ever recall a deer even acting remotely alerted to my prescence after cutting my trail around my stand when I used that cover scent.
Think about it.......what animal is more ignored by game than a squirrel?
