I noticed that some people questioned whether or not this was worth doing, because if someone wanted to remove the tag they could do it no matter how much trouble you went through.
While this may be true, a large gauge wire can be pretty discouraging, and wimpy little chains appeal to people's laziness. Having your tag well attached decreases the chances of someone bothering to remove it.
Also, I came across a travel bug today with the original chain, and it was broken! I couldn't tell what item the tag was supposed to be attached to, I had to guess. Luckily I guessed correctly. The chain must have been damaged somehow, maybe due to rust? There was a lot of water in that cache. Regardless, the point is that no one wanted to remove the tag, and it ended up being removed anyway! Replacing the chain with something more durable is a very good idea.
