"Well, I think the dryer sheets would be considered a cover scent, and not bait, since the bears would have to eat you before they could eat the sheets. "
It doesnt have to be edible. SCENT/lure is illegal for use during bear season as well. Id say apple or acorn scent would qualify.
Restrictions
It is unlawful to 1) kill a bear in a den; 2) use a radio to locate a bear to which a ratio transmitter has been attached; 3) hunt on areas where artificial or natural bait, hay grain, fruit, nuts, salt, chemicals, minerals, including residue or other foods are used, have been used, as an enticement to lure wildlife within the past 30 days;
4) USE SCENTS OR LURES.
Dont know that anyone would notice or care if you had your clothes dried with such smelling dryer sheets, but could see potential problems with hanging them in trees.
