Ive been on the amtrack plenty of times and Ive never seen any searches. Also I rolled one up on a amtrack before. A lady in front of me said it smells like marijuana. I lean over in the middle isle to see who said it and I take a whiff and say yea it does smell like marijuana. Nothing ever happened, except I left my wallet on there when I got off. I toke my wallet out to get my papers out of it. Just double bag it and stash it away. Oh yea and dont go on smelling of buds.
