I've noticed the Portland police using more bicycles and motorcycles, probably to conserve gas. Their budget must be taking a hit from the gas prices just like ours is.
Look at how empty the street is in the second picture. That street is not closed, there just are not many people driving around during off-hours any more.
Speaking of closed streets though, I've heard rumors that the police do plan to close some streets completely, and on others they will set up checkpoints and only allow government vehicles through. If that's true, I'm not sure what the goal of it would be, except maybe just another way to discourage people from driving so gas is available for emergencies. But it is still just a rumor at this point. Can anyone confirm it?
