Here are the files for the next Viz Challenge. The UT State Park data is the core data that you should use. The fire data and any other relevant data can be added to your workbook to help you tell a story. For example, I would think that finding lat/long data and adding it would be very useful.
* The file that was loaded to the open data site looked to be incomplete for 2009. Other years that are missing are 2010,11,12,14.
Let me know if you have any questions about the data or the challenge.
