Mikes concern is more in line with mine. The way the tree huggers have set things up for R12, getting caught bringing R12 over the border wouldn't be much different than getting caught bringing cocaine over the border.
I detest the laws regarding R12 probably more than anyone else on this forum, but I also detest the idea of going to jail.
I've only seen the inside of a jail when transferring a prisoner while in the army, never as a guest. I intend on keeping it that way.
If you guys want to take the risk, I say go for it.
Best of luck,
