Alberta in HDR - road trippin'

Normally I do not like HDR images.  Let me clarify that... I do not like overly tone mapped, sharpened HDR images that you see all over the internet.  To me HDR should look like almost indistinguishable from an non-HDR shot.  So I wanted to see if I can attempt it myself.  So I took a little road trip into the unknown little roads north of Edmonton.  I left a little late, and was chasing the sunset, looking for good spots along the road.  So in this set, there are 1 image which is not HDR.... can you guess which?  Enjoy!
