That's an interesting question. The Property I hunt has both overgrown logging roads and very clear cut ones. I personally don't see the difference in the deer usage. There are 2 ways of thinking, 1. deer will take the path of least resistance. meaning the clear cut road. On the other hand 2. Deer will use the overgrown logging road as cover. and not to mention overgrown usually means less usage from humans hence less pressure. Alot of times i like to cut open old roads along thick brush because it opens up a natural funnel for the deer to use. As to which is better...i dont know, i suppose each has its ups and downs and it also depends on the surroundings and how you want to hunt it.
