Is there 24 hour security?

Pretty sure there is, it is a safe place to stop

Its open 24/7 but i no sure

Yes

Twin City Security is contracted by the State of Alabama, Department of State Parks, and is at the Rest Area 24/7.

I don't believe so.

I didn't notice security there . There was somebody there cleaning the restrooms .

I didn't notice security

It's open 24 hours so I assume the security guard is there......
