When you're in the procession, with the priest and ministers, it's best to just "follow the cross." First of all, it's raised high, so you can see it to follow. Also, the people in the congregation seem to open up a way for it, so if you're behind the cross, you get to move along, too. I've also thought that maybe the altar server could lower it like a lance and charge, but of course that's not done.
But the cross being the cross, you know that you'll get behind and lost in the crowd. You might get jostled. However, if you keep your eyes focused on that cross, you'll find your way back.
Take up your cross and follow Me” (Matthew 16:24; Mark 8:34; Luke 9:23)
