He said in one interview with Howard Stern because he didn't have one he is able to keep some sense of anonymity. I suspect there maybe more to it. Such as he either doesn't care for the style or it just gets in the way. Not only drumming but also in ranching.
When the weatherman/woman quotes the weather as cold but fair...what are they referring to as "fair"? Is that the wind speed?
What Rooster said. Fair weather is nice, non-rainy/stormy weather. Like our local weather is currently warmish and NOT fair at all.
So cold but fair means cold but no precipitation and minimal to no cloud cover, partly sunny etc.
