It seems the best-case-scenario is to dramatically reduce deer densities in CWD areas, if the spread is worst in areas of extremely high densities (deer/elk farms, high pop units). West Tennessee just got some confirmed cases, and they practically extended the season and got rid of bag limits in a handful of counties. It seems to be the most sensible approach.
Barring a more aggressive implementation of such a policy in Northern Virginia. I fully expect a catastrophic wipeout of deer populations in the Washington, D.C. area within the next 15 years. Northern Virginia counties, which generally have the highest deer densities, are where the "CWD containment zone" is. But assuming the infection hops the county lines into Loudon and Prince William Counties, it's only a matter of time before Rock Creek Park in DC, with its 100+ deer per square mile, gets littered with corpses and buzzards. I hope that DC residents then come to realize how stupid they were to not allow a liberal issuance of archery tags.
