Safety comes first. :)

They do look familiar. I was thinking of Chris Colefax's City Include 
File. But it is so long since I used it all I can remember is that they 
were very rectangular.

Another thought that struck me would be to use Runes Particle System to 
make the cloud container. It can flow around obstacles.

Hmm! not really. It did take a few years to lay a gas pipeline after 
putting down the oil pipeline. Remember in the early days it was very 
expensive and there was not that much revenue coming in. Unlike the way 
Norway developed their oil and gas. The UK gave tax concessions to 
private companies to develop the oil and gas fields. And their bean 
counters were more interested in profits.
