First time in a pit at Aftershock

I never went to a metal or rock show in my youth, I started going to Aftershock in 2017 about 8 years after a horrific car accident. I walk with a cane at events like this because of the amount of walking that I do. This might be my last chance to go to aftershock and I thinking about getting into a pit for my first time. I can walk without my cane but running is a little bit of a stretch. Just wondering if anyone has some advice on what kind of protocol I should follow as far as trying my first pit experience.
