I've seen a lot of deer forage in burned out areas. I've even seen them foraging while the fire is still smoldering. I've heard they will eat charcoal (anyone know about that?) and I know they like the green shoots that sprout later on. Generally I've seen them in these areas when it's dark, probably because they are bedding in cover and need to travel a good distance to reach those areas. If you can find a good spot to set up it seems like a decent strategy. It might be a good area for years afterwards, too. One of the most active spots I know here in FL is an old logging tract. It's really brushy, so it's hard to hunt, but the deer love the young, low trees and shrubs.
