The 2012 Duluth Airshow took place this weekend and a good time was had by all, dispite the 40F temperatures.
I particularly enjoyed the F4's ( camouflaged planes in the first picture). I flew in the back seat of the reconnaissance version of this plane for 20 years.
Here are a few images taken Saturday.
Additional images are here.
