I know a person from CA that grew weed and had a good crop, so good he wanted to sell some of it. So he loaded up and hit the road headed for Texas, stopped for fuel (truck stop in Nevada) and sold a bag to an undercover agent, and when he got to Texas he sold the rest to another undercover agent. Yep he went to jail, and all those pretty buds, well you can guess what they did with that.
IF I am to cross a state line I carry nothing!
