William H. Martin (Marty) has been studying the timbers there in VA. for a number of years. There are still some pockets of horridus interspersed in the rugged terrain there. Timbers are protected in VA. and most states are very ridged in enforcing violations. Given that these snakes are a K species, collecting even one can have a detrimental effect on the entire population. If you are just going for observation purposes I would suggest getting a guide on local herps and see what counties they are found in and start from there. Be patient as they are very tough to spot in the wild.
