I see you note the issue with poison ivy. For any Shenandoah pages I have created that require some bushwhacking, I note that since Shenandoah peaks can be hiked all year round, that winter is the best time to bushwhack, even for rock climbing. Poison Ivy is a real problem in Shenandoah, and makes bushwhacking very risky from March through early December.
