DDT is THE weatherman.

[Valker]

Getting to ride cross country with Bruce as a guide is fantastic. He was a guiding us around rain like nothing I've ever seen!
This is a talent I am very thankful for and really enjoy.

  Nice, I bet he has all kinds of experiences trying to avoid the rain. Ya'll be safe.

I bet DDT IS a good weatherman....
A fishing guide has to fish everyday to know where the fish are and hunting guides have to hunt everyday to know where the game is....
To be a good weatherman you have to deal with the weather everyday to be good at reading whats in the weather ahead......and Bruce is out there amongst the weather every day.
