Did a little cross border shopping yesterday and came back with a trunk full of parts . One of the items was a new in the box NOS Nitrous kit . declared to Customs what I had and the first thing they asked was if the nitrous bottle was full . They seemed to be VERY OVERLY concerned about the bottle being full or not . Is it against the law to bring Nitrous across the border ??? Because...I plan on getting refills in the States because of the price difference . I should of asked but didn't , I just want to get the hell out of there .
