I was out bass fishing yesterday...caught 4 legal keepers (a 2 lb. bass was in the mix

But I noticed sumtin rather weird. First of all, I was using a plane Jane bass jig. That's what they all bit on. But when they bit, they didn't bite it like normal. They didn't attack it like most do. Then again, it was in the mid-80's so they might not have been really enthused to bite. But...any answers would be nice...thanx
