Where is the reserved lawn upgrade area? Is it worth it?

Actually some bands do offer a reserved lawn area. It will be roped off in the front center portion of the lawn. I think price determines its worth.

If you get there early enough but its not bad at all especially if its a good concert

All lawn is General admission

There are reserved seats.

There is no reserved lawn area. It is first come first serve.

I'm not aware of one to be honest. But lawn is lawn and a good view from anywhere
