Re: Carrying jo, bokken on Amtrak?
This reminds me of the time when I and five friends went whitewater kayaking in Nepal and (as a favor to our outfitter) smuggled in something like a hundred raft paddles as a favor to our outfitter. We thought we were through and clear, when a customs official asked what's in the big box. Best possible response, from the youngest-looking member of our group, looking all big-eyed and excited: "Oh, they're RAFT paddles! We're going WHITEWATER RAFTING!" Worked like a charm.
...but, ya know, they weren't my paddles, and if we'd been busted, the duty, fine, and cost of the paddles was all on the outfitter. I'd feel differently if it was my beloved bokken.
