You might have better luck in MD
[QUOTE=MmQuickX;2163552]Ahhh, just saw this after I replied to Bunker Buster's post.
I feel like I've gotten the hang of the Metro over the last two weeks or at least how to get back to my place and to work, etc. I just feel like a lot of places are just REALLY far away, namely the ones in Arlington. The BP ads are too vague, as Arlington is huge and I'm not even sure if I can get there completely thru the Metro.[/QUOTE]From where you're located (Columbia Hts / Petworth) you might have better luck checking out the scene in College Pk / Greenbelt (Grn Line) or Takoma Pk / Silver Spring (Red Line). Those are not my areas but if you read through the applicable MD forums (Montgomery County & Prince George's County) you'll find more info.
My area is Northern VA, which is reachable by Metro for you but it's not a quick trip. Weekends might be easier although the trains run less frequently. You're right that Arlington is huge and providers can be really stupid about how they post their incall location. But Crystal City is one area with lots of girl-friendly hotels within walking distance of the metro. Another is Tyson's Corner and the new Silver Line opens this Saturday which will take you right into the heart of TC. If you spot an interesting provider but her location is unclear, you might just have to call / email / text her to clarify. Asking if she's near a metro station is a question she should be prepared to answer.
Good luck and keep us posted on your progress and what you find. Keeping the info flowing on this board is what it's all about.
