Not Exactly Following the Yellow Brick Road
You've heard of ambulance chasers (not something I recommend becoming), but today you get to be either a snow plow chaser or a garbage truck chaser.
To properly celebrate January 4, following a snow plow is preferred, but obviously that depends on the weather in your locale. If it isn't snowing hard enough to bring out the plows, you can choose to tail a garbage truck instead.
If you're able to tag along behind a snow plow, your driving should be fairly easy. After all, the plow has just cleared the way for you. Do be careful not to get too close. Sometimes they do have to back up.
If you can't do the plow thing, find a neighborhood whose trash pickup day is today. I think following a recycling truck (as pictured) is also allowed to celebrate this day. You can look it up before you head out just to make sure.
Now staying safely behind one of these vehicles is a little trickier. They stop and start a lot more often than a snow plow. They probably back up less though. You also probably don't want to get too close because the garbage truck driver might think you're weird (or dodgy?) if he notices someone tailing him.
The time factor of 3 hours is a suggested minimum. That said, if you can only spare an hour or two, no one will look down on you for shortening your trip. On the other hand, if you can manage more than three hours, no one will think any more of you either.
If you start to follow any of these vehicle types and see that they're leading you back to their "home base", you've struck the jackpot. That's considered the "holy grail" of snow plow / garbage/recycling truck following!
So if you time it right - nearer the end of a snow storm or the end of the day - you just might get to see where these trucks hide out most of the time. How cool is that!
