How much is the extra checked bag there and back going to cost you? It may be cheaper/easier to leave it at home and buy a (collapsible) pole when you get there?

You may even be able to bring a collapsible one back in your carry-on. I have flown with a photographers telescopic monopod in my carry-on. Its basically a much bigger heavier collapsible hiking pole, complete with metal spike/rubber foot. I was expecting grief at the x-ray station since it would make a damn good cudgel if the need ever arose, but it didn't get a second look. Admittedly that was a domestic flight here in NZ where security theatre isn't a multibillion dollar industry.
