I looked it up on google maps. It does look pretty complicated. Looks like I have to go straight across the road after the exit. Then find a place to park. Then to leave, I have to freaking go right on that same road to get to the ramp for 270 NB, what the hell kind of design is that!?
It's a bit of a filter I guess, keeps the manassasites and thurmontonians from overunning the place. People in these here parts drive around with bumper stickers that say "Don't Colorfest Montgomery".
