The travel tag already has zero questions (and strangely, two followers).
This tag is uselessly broad on a site which is about travel. It should be blacklisted so that it cannot be used in the future.
I acknowledge that burination and not using the tag is the usual solution to prevent tags from being used. Since this site is so focused on travel, I assume the tag will be back even after we remove it form the current questions. In fact, the tag has only recently reappeared after it had been...
burned with flames so tall as to make it an example for all other similarly useless generic tags.

As such, I think block-listing is warranted. :)
