A random thought I had this morning:  There are a lot of trucks that idle in our development.

I woke up this morning to the sound of, well, I don't know what kind of truck.  Whatever it was, it was making some grinding motory racket outside at 6am.

This past week, some neighbors have been having work done on their roofs.  The trucks that pull up outside simply leave their engines running.  I'm not sure why.  Maybe they need to be able to make a quick getaway if it starts to rain and they're on the roof?

The groundskeeping crew leaves their trucks by the side of the road.  They're not idling, but the mowers and the leaf blowers they use all day are nearly incessant.  Especially the leaf blowers.  I have a theory that when the crew gets tired, they just turn on the leaf blowers and wander around.  Outside my house.  Where I'm trying to concentrate.

It seems like just in our neighborhood we're consuming a crazy amount of gas, probably unnecessarily.  If there are communities like ours all over the world, that's simply a stupid amount of gas being wasted.

I think science should invest time in genetically engineering energy-producing grass.  Grass doesn't seem to be doing anything else than eating up our fuel supply and wasting our weekends cutting it.  Maybe grass should work for a living?
