With higher temperatures world wide, Austin has no secret weapon against the heat. Exacerbating the problem is the lack of shade in Zilker Park. The park is grassy during the early summer, but in previous years grass is trampled during the festival and the conditions get dusty. For 2006, ACL, working with the City of Austin, installed a massive irrigation system to eliminate dust concerns during the Festival. Organizers do not want to move the festival into October due to conflicts with hotel room availability on UT football weekends, increased chance of rain, and the reduced chance of booking bands on summer tour. The festival does allow attendees to bring 2 factory sealed water bottles, and has reasonably priced food and drinks compared to other festivals.
