dry ice coleman extreme cooler...done it a few times... pack it well and toss some fish on the top... I even got searched once and the cops didn't even try to go beyond the fish layer lol....the cali ag peeps didn't search my uhaul last time .. just made me open the back and looked in asked a few questions and I was on my way.....
You were fortunate, as most of us are most of the times. But some cops are like rabid dogs, and they don't all play by the rules. 99% of the time, that method may work, but I guarantee there are people sitting in prison after getting caught transporting herb over state lines.
