I would suggest going to your local university and looking up this paper:
Clark, A.M., P.E. Moler, E.E. Possardt, A.H. Savitzky, W.S. Brown & B.W. Bowen (2003) Phylogeography of the timber rattlesnake (Crotalus horridus) based on mtDNA sequences. Journal of Herpetology 37(1): 145-154.
It will atleast help all those opposed to the Timber only monotypic classification get a better grasp of the most current research instead of discarding something they may or may not have read.
Here is a link to the abstract for the paper:
http://biology.bangor.ac.uk/~bss166/Updates/Crotalinae2003.htm
I agree with Chance and others as well as the authors of the paper. Just because they look different and have behavioral adaptations to a specific habitat does NOT mean they are separate species. For example, lepidus, abyssus, concolor, viridis, and cerberus all have variation (some to a great extent) within their classifications and of course there are a few variations in corn snakes as well...... ;-)
Morphology is NOT the only method to obtain systematic certainty. Like Chance said there are a few differences between humans that have different geographic origins.
The use of Canebrake or Timber is helpful in getting an idea for general region of origin but that is really as far as it goes. And I've seen a few specimens in my day as well.

Can someone identify this snake for me?
http://www.fotop.net/KingGhidora/snake
It seems to have the shape of a timber rattler but some things threw me on this. I'm not that knowledgable on snakes. The snake flattened out it's neck when it felt threatened. I couldn't make out a rattle from the photo though. And I was taking the photo from a distance obviously. I have a few other photos I could post. I also have some video.
