Hey guys,
I thought it would be interesting to see what everyone thought.  Based on what I've heard, ZOB seems to be the busiest en-route airspace (CTR) airspace in the US in real life.  What about VATSIM? Has anyone ever thought about that?

I say ZDV.  It seems it gets the most overflights to the west coast, but I'm wondering what everyone else thinks.
