Once we get to Emmittsburg we have a choice of how to go to Hanover. Either through Taneytown (Tawny) or up 15 to 30 or one of the other roads that can go east. If we want to go to North Hanover and take 30, a 10 mile drive turns into 20-30 min. So, yea, not real traffic but despite that area being 35-40 miles from our place it still takes us over an hour, and I drive fast.
Your experience of Baltimore traffic is why I will not take a job any further south than Frederck. 270 is even worse re: DC. I was in and around Hanover and Spring Grove back in the early 90's and yes, even back then many people were Baltimoreites living in the "suburbs". LOL.
