Depends on what you mean by "travel". All the southern states have more than enough wild hogs and most of them you can hunt year round. States such as Texas have no restrictions whatsoever. You can use anything that can kill, any time day or night as long as you have the landowners permission. Your best 4 options are, Texas #1, Georgia, Lower Alabama, and Florida. South Carolina and Tennessee offer some pretty good hog hunting as well but they are a bit more restrictive on licensing and times.
