Suggestions on cab companies for a Monday morning?

or would a car service be the same price?

If you were going early enough, I would drive you to my office and you could metro from there. Can you cab to the metro and go in that way?

Thanks for the offer!

Our plans have changed, so I am going to drive to West Falls Church metro with my folks and metro in. Mom is going to k street and Dad and I are going to take pics for his kindergarteners on the Mall.
