She rides the Metro (subway) to/from work. I had thought she would ride buses. It took a day or two for her to find a place to get a Metro card that she could put money on so she wouldn't have to pay cash every time. It sounds like she will need about $22 a week to get to/from work.
One her biggest problems is the total lack of Dr. Pepper. She is finding it very hard to find her favorite soft drink. She did find some at a store but she didn't want to lug it all the way back to the dorm with all the food she was getting.
