That sounds like a very enjoyable endeavor! I was wondering, what are the benefits and drawbacks to flying a lighter-than-air ship under 1,000 feet? Or even closer to the ground/tops of buildings? <500 feet? Are there simply too many regulatory issues?

I have a dream that some day there will be airships floating around cities, ferrying passengers and freight, and they will float only 30-100 meters above the tallest buildings.
