Sigh, you got some decent and some awful advice.
You can hunt black bear alone all you want (unless using predator call). Otherwise how could anyone elk hunt, deer hunt, etc etc...when there are bears around? OH NOES!...It's being in grizzly country alone that's not the best idea. So don't overreact. And screw everything that guy said about sidearm proficiency, too. You're probly hunting with a rifle, so just be good enough with said rifle! Carry a revolver if you want, not a bad idea for backup, but it's not a miracle tool.
Black bears don't hunt you. Awful words of "advice." Black bears are rightly fraidy cats, for the most part, and leave when they smell you. That's the their best sense - smell. So you can see one, but eventually there's a chance it'll smell you if you're not careful, and run off. Sure, watch that bear to see if it's a sow with cubs, and there's the tiny chance it's an insane bear...but that's life in the woods.
Just wander around and look for bear scat, look for the food sources...right now the berry rush is on here, and there are bears all around, they get very casual...just get out and have fun learning as you go. Carry bear spray and be a man, find them with your eyes...
