Lawn seats are not great. You are quite a ways back, and while to roof supports don't block too much view, you do need to jockey for a good spot to minimize that. Also, if you care about bands that may go on before the sun goes down, the stage is covered and darker than the lawn and outer row of sets so it can be a little harder to see. For rowdier shows, the lawn is where the rowdiness is concentrated, so consider that if that matters to you. If you really, really want to see the show and they are all you can afford they are fine, but sections 1-8 (under the roof) are going to be a much better experience.
