One fish characteristic that I only see happen in Fall is a strict topwater bite. On days when it seems they are just completely shut down, won't touch a jig or anything else, you can start throwing a buzzbaits or a spook and absolutely tear'em up.
Any other time of the year if they are active enough to bust topwater stuff then they'll also eat spinnerbaits, flukes, cranks, and just about any bait you choose to devote time to. Not so in the Fall.
