I am coming up for the festival of fire at the end of the month. I plan on bringing a friend with MS, are the grounds handicap friendly? Like wheelchair accessable?

You should be ok. I the camping area is pretty open and level

All-terrain tires are highly advisable. I've seen it done.

The only bathrooms are porta potties. The roads are dirt and gravel. Accessable? Yes. But it will be work getting around, especially if it rains

Thanks guys, he'll be happy to be out and enjoy life for a bit, even if only a weekend
