RDR also owns his own construction business and his wife her own salon - so it's not just snakes that's making his income.
NERD lives very frugally - no fancy cars, high mortgage, it's not a koosh job - I've been behind the scenes twice at their facility - it's a LOT of sweat an a LOT of hard work while the economy tanks and the cost of living goes up. And a LOT of stress - seen it first hand.
