If your in Moco you can catch them when they play Frederick. I doubt they would go outside VA. Near Westfields and Chantilly would be great!
Although 28 could be a nightmare. Face it. Traffic in this area is bad enough everywhere. So ANYWHERE you go will be a problem. Lower FFX is also a problem with the BRAC moves to Belvoir.
Being in Manassas I like the location! I still dont get to many games due to my Nats schedule!
