College venues with college distances (especially to power alleys and centerfield) are very different than most of the high schools, although Westfields dimensions are a novelty as a ballpark. It definitely favors hitters with no foul territory and the high wall in center turns would be outs in other parks into hits.
The VHSL likes this idea of AAA Jubilee. This way they get to get all of their administrators together in one spot, have their own organizational meetings, and and sample some of the s****r, some of the baseball, some of teh softball, lacrosse, etc as well.
It's not a bad idea, it's just different.
Westfield venues are first rate. Parking is no problem, as if the high school lot isn't big enough, the rec center has parking and there's plenty of office building parking within a short walk. Traffic coming in to DC will be fine as this is outer suburbs. Just cut over from 95 coming north prior to the Beltway and enter Chantilly via Route 28 or 29. Plenty of hotels and restaurants in the area, as well as Capital Expo Center (don't know what show is going on there this weekend), plus Smithsonian wing at Dulles all within 5 minute drive.
