November is prime time for mule deer in the West--the later in the month, the better. In mountainous regions, deer commonly migrate from the high country to winter ranges where they're far more accessible to hunters. There's one caveat, though: Mild winters can delay the migration, and the deer might not show up until the season is over. It's a risk worth taking. There's nothing much better than sweet, crisp mountain air in late fall and some fresh snow to help you track your buck.
