For the cheapskate who's always wanted to dabble in aromatherapy, and because "road aromatherapy" or "road rage smells like Christmas" didn't seem catchy enough, I present ROAMATHERAPY.
- Go to your local live Christmas Tree seller. This might be your local supermarket with trees and wreaths out front, or some guy selling these out of a tent along the roadside.
- Grab a discarded sprig of Douglas Fir. You also could ask nicely, but I doubt the seller would mind if it's already fallen away from the tree.
- Using Duck™ tape, a chip clip, or a convenient crevice between the vent and the dash, secure the sprig so that hot air from the vents wafts across it.
- Turn on your car's heater. Akin to the principles used by various aromatherapy diffusers, the pleasant aroma of the Douglas Fir is expressed from the plant material into your car's interior.
If your memories of Christmas are gloomy or nonexistent, hopefully this will bring you some of the Christmas cheer I associate with the holiday that is far more enjoyable than its rampant consumerism.
