>>442989Thru-Hiked the AT and I hung a bear bag one time in 6 months of hiking. Saw plenty of bears, never had a problem with them.
I know people who had problems with bears, but to me it wasn't worth the effort of doing it every night.
One weekend trips and the like (especially if I'm with inexperienced hikers) I'll hang a bag just so people don't get stressed out.
