Its that time of year

Its winter. The weather is nice, the holidays are plentiful, and the blue hairs are out in force. Sure, I live in one of the nations retirement capitals so I should expect to see them on the road but now we have been invaded by the most insidious of blue hairs: SNOWBIRDS!
I hate driving snow birds. You may be asking yourself how you could spot one for yourself.
Here are the basics:
Identify the slowest vehicle on the road around you. Notice how they are driving like they have absolutely no where to go, and even if they did they don't know how to get there, and to top it all off, they don't care when they get there. Yah.. its a blue hair. How do you easily tell a snowbird from a normal blue hair? Look for out of state plates. Not all plates apply here, Texas, Florida, and New Mexico usually just mean they are visiting. Their state is already nice and warm, they have no need to move to Arizona for the winter. The ones you have to look out for are Oregon, Idaho, Montanan, the Dakotas, and all plates Canadian. Be especially wary of Canadian snow birds. Not only do they have the same oblivious driving habits as other snow birds, but they also have an innate distrust of our measurement system and will often drive based on kilometers instead of miles. Sign says 35 mph speed limit gets magically turned into a hideously small number because they can't do the conversion in thier head and don't want to deal with "foreign" driving offenses.
