It looks like the USGS EarthExplorer site, which often has NC lidar, has the 2011 Indiana Aerials, which are available on the Indiana GIS site, but with a slighty less wonky download interface. (For example, I can't get the bulk download application to run properly, but if you download all the hits, you can usually get the area you need without holes.)
Zoom to about where you want---one click too far in is best.
On the left, click, "Use Map" (or something like that). The screen with turn red. Now zoom out until the four corners appear. Adjust them to your area of interest.
Now click "Data Sets" and Select "Aerial Imagery" and then check the box for "High Resolution Orthoimagery" to get the 2011 Indiana aerials.
Now click "Results" to get the list of images. You have to figure out the download interface. I always make sure I get at least one metadata file so you can verify projection and other details. When I'm looking for other aerial photo options, like the approximately annual agricultural set (lower res, but good for new details you can get any other way) or the old old black and white DOQs, you check a bunch of boxes in "Data Sets", but then you have to pull down and click select each data set in the results display. For example, if it says, "No results" be sure to pull down that list and go through each option to verify "no results" (or a list of results) for each box you checked.
