Yes,I"ve done it,but you sure better get your walking shoes on!
Watch from the very back of Hollywood Hills near the exit.
As SOON as it ends IMMEDIATELY begin speed-walking down the exit and KEEP ON SPEED WALKING,using the BWI shortcut until you reach the IG and then watch from the English Channel Bridge.
The 30 minutes you will have is just enough time,if you SPEED WALK as fast as you can the whole time-not something I would do a lot,but fun to do and accopmplish once.
