GMR Friday: Inversion...

Whenever the temperatures spike here in So Cal we can expect this little thing known as the inversion layer to show up for the party. The layer is like an invisible cap sitting on someone's bald head. It sits up there and presses down, keeps the heat in, not to mention all the crud thrown out of exhaust pipes, smokestacks, and what have you. You can't see the inversion layer, but you can see all the brown gunk being held in by it. Fortunately you can ride up into the mountains and rise above those two layers - the gunk layer and the inversion layer.
