When I was in Yellowstone a few weeks back, the morning I left since it had rained the day before there was some awesome fog/mist in the morning. I got a few keepers I think, this is one of them I hope.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
