I've been apart of deer drives before. I've actually killed deer on deer drives. Don't correctly, they are effective and safe. You might more of a chance of dying falling out of a treestand.

I do however, save deer drives for late in the season...usually the closing weekend or last few days.

Also...they are very effective on islands where people pressure is limited because you have to have a boat to get there and also, the deer's movement is restricted because it's an island for goodness.
