My wife and I are going to Yellowstone in September (not a "fishing trip" per se, rather a 35th anniversary gift to ourselves; she is not into fishing). But of course I would like to get in a little fishing. Of all the rods I have have, the only one that fits in the luggage I own is a 6'10" 4-piece 4-wt, but I don't know if that would be adequate for the trip. I got to thinking about tenkara, and the beauty of being able to put the thing in a small backpack, and not having to carry a reel, etc. Think that would be sufficient for fishing at Yellowstone? I would rather buy that than a bigger piece of luggage (though explaining why I need an 11th rod could be dicey).
