Has anyone used a knee scooter before? / Ground question

It’s gonna be my first time at Bonnaroo and I’m showing up rocking a knee scooter, I tore my calf recently. Has anyone done something similar? I’m wondering what the grass is like in Centeroo and if you thought it was pretty manageable. The only other option is to use crutches (which sounds miserable) or trying to put some bigger air tires on the scooter. And advice or experience is greatly appreciated.
