MBZ. Excellent idea and I still believe that it should be moved or widened into the RIC airspace. This as I said before will allow easier Navigation, especially at night and the possibility of raising the upper limit. Of course this will only offer short term respite.
What's going to happen when the new 'Badgeries Creek' opens or RIC becomes SYs' second airport. Everybody moves from BK to CN, HOX gets closed down?
