Wow, the hottest part of the year. Stay to the mountains brother, less humidity and lower heat. Hopefully I will be in town when you guys come by DC. Others have mentione the Blue Ridge Parkway and Skyline Drive, I highly reccomend them too. When headed north from DC, cut through the center of Pensylvania amoungst the mountains there and on into New York State. Riding in NYC is doable but not a fun experience, nor is riding in DC proper. Still, both cities have many cool attractions to see and places to visit. If you go to either of these two cities, try to be there when nothing big is going on. Wednesday is usually a good day for most DC events not to be going on. Its walking speed to leave DC on any Friday.
