Making the rounds today is a Tea Parties Guide to DC. So just what does this guide say?
DC's population includes refugees from every country, as the families of embassy staffs of third world countries tend to stay in DC whenever a revolution in their homeland means that anyone in their family would be in danger if they went back. Most taxi drivers and many waiters/waitresses (especially in local coffee shops like the Bread and Chocolate chain) are immigrants, frequently from east Africa or Arab countries. As a rule, African immigrants do not like for you to assume they are African Americans and especially do not like for you to guess they are from a neighboring country (e.g. Eritrea, Ethiopia, Somalia) with whom they may have political or military tensions. It's rare to meet anyone who gets really offended, but you can still be aware of the issue.The emphasis above is mine -- since the nearest Metro stop to my home is the Green Line. So I guess that makes me a Coffee Drinker Partyer! Was there ever any doubt?
Many parts of DC are safe beyond the areas I will list here, but why chance it if you don't know where you are?
If you are on the subway stay on the Red line between Union Station and Shady Grove, Maryland. If you are on the Blue or Orange line do not go past Eastern Market (Capitol Hill) toward the Potomac Avenue stop and beyond; stay in NW DC and points in Virginia. Do not use the Green line or the Yellow line. These rules are even more important at night.
