       | covered on top.

             | It's worth mentioning that the enhanced driver's licenses
             | and state IDs are still valid, which tend to be easier to
             | acquire and require far less paperwork if one is already
             | getting a license/state ID, so residents of the more
             | populated border states have a somewhat more seamless
             | option.
