At this holiday time, what could be more festive than driving all over the place in your car? Of course, at today’s gas prices visiting far-flung friends & family can be expensive. A partial solution is to drive a few miles out of your way and buy cheaper gas.

Does raising the minimum wage have any bad side effects? George Will, in his op-ed piece in yesterday’s Washington Post, gives about fifteen reasons why raising it is the wrong thing to do.

When done properly, numbers provide a profound glimpse into the future. Here are two graphs from a Washington Post story about the possible implications of China’s recent changes to their “one-child” policy.
