Some thoughts, and welcome to the forum.
o Present a clean and neat appearance (optional);
o Be polite if stopped by LEOs, but don't give up your rights;
o Always run a voice recorder when OC-ing in case you need proof of your good behavior, or any LEO or "anti" encounter;
o Wear a good retention holster;
o Keep good situational awareness. Note where you're sitting, standing and walking;
o Be aware of local ordinances;
o Consider carrying a wallet card with helpful info on the legality of OC-ing.
HTH, and have a great day.
