I saw your replies and questions below and didn't want to put this down there in case it scrolled off before you could see it. I'll try to answer some of your questions.
Best time of year down there, IMO, is the first time in the Spring it stays in the 70s overnight for four or five days straight. Even better if there is a good rain early or middle of that period. This is usually early to mid April, can be in March. Second best time, and maybe best for vens, is Autumn.
Don't worry about running across hunters on wildlife management areas or other hunting grounds now. Turkey season ended in April. The next time folks will be in the woods hunting anything on Boykin, etc., is probably going to be when bow season starts for deer in October. Actually you're not likely to see anyone out in a public hunting area until then. You'll have pretty much anyplace you go to yourself. People-wise, that is. You'll have plenty of bugs to keep you company. I don't think you or me checking around for snakes on a wildlife management area during hunting season is a safety issue (as long as we're reasonably careful) as much as a courtesy issue, but either way, I tend to avoid herping during hunting season on public land on which hunting is allowed. Heck, there's a good chance I'll be hunting then too!
If you don't have it, I highly recommend you purchase a copy of "The Reptiles and Amphibians of Alabama" by Prof. Robert H. Mount. Buy the 1996 reprint; there are some updates from the 1975 original edition. You can probably get it or order it at one of the big bookstore chains in Mobile, and you might try the bookstore at Univ. of South Alabama. It is published by the Univ. of Alabama Press.
Alabama has one of the most varied sets of habitat types in the eastern U.S. It has an amazing variety of herps. Although there are of course a lot of developed areas and more development taking place, Alabama has, compared to places like most of Georgia and peninsular Fla., a lot of "wild places" left. Right there in Mobile County you *could* (though the odds are pretty long) find all six of the venomous snake species present in the east. There are also numerous species that are represented by several subs and intergrades in Alabama - it is kind of a "crossroads" for reptiles and amphibs. Get Prof. Mount's book. You'll love reading it even when you're not in the field, maybe especially when you're not in the field.
