When Mississippi had them I kept it in the trunk with my proof of insurance. You can't put them on the windshield, so the LEO's knew we should have them and ask for it. I did run into a road block one time that they asked me to show my papers.
Thankfully Mississippi did away with the inspection sticker scam about 5 years ago.
