Arlington VA is definitely, from what I hear, rich in EFs and more traditional OF Masses (I’ve read of several churches there recently that renovated the sanctuary, reinstalling altar rails and rebuilding high altars). As has been said, the general rule of thumb is to find other potentially interested people first, then approach the pastor to request (humbly) that an EF Mass be celebrated to accommodate your legitimate spiritual aspirations. Be aware that your group may need to undertake considerable expense to make it happen, so be ready to support the priest in doing so if he’s willing. Among other things, he will need to be trained to say it (a workshop in the area would be best, or failing that a DVD of the sort put out by the FSSP), a traditional Missale Romanum, ideally (but not necessarily) Roman vestments, altar cards, a maniple, etc. Also, if you expect high Masses to be celebrated, think about organizing a schola. Finally, take the initiative to advertise the Mass and bring in people from elsewhere.
Be aware that it is unlikely that you will get an EF Mass on the schedule early on. It will be necessary to show that there is stable interest first (I’m given to understand that the diocesan chancery has to approve a change to the Mass schedule). More likely, your pastor (if he is supportive) would celebrate the EF Mass privately and invite you and the group to attend, and perhaps do this a few more times. If interest is stable, he can look at putting it regularly on the schedule.
