The deer I see around where you're hunting (If you're hunting where I showed you) are staying consistant, even in this heat. Stick to evening. some movement in the mornings but, they're coming out at dusk. This next week is supposed to be 15-20 degrees cooler too. Probably closer to what it'll be in early Sept.
I think the hunting show question is that blackie racks aren't what other species are. Harder to hunt them, harder to get a hunt on film, majority of the country doesn't/won't hunt them. Bottom line, there's no sponsor money in hunting blackies on TV
