I don't know what it is, but I commute about 38 miles one way to work 5 and 6 days a week. I know that I rarely see deer to and from work anymore. I used to see 10 to 20 every day during the winter. I only remember one day last year that I saw more than 10 deer driving home at sunset. It might be habitat, because nothing looks like it did 20 years ago, but I think there just aren't the quantity of deer in pockets of Alabama anymore. Maybe in 10 years, with some changes, it'll be back like it was in the 90's. I just hope tight rolled blue jeans, spiked hair, and sebagos don't come back in style.
