Hey Marcy, how very cool. I like what you captured in some pretty difficult lighting situations for waterfalls. I am trying to think if I have been to Buffalo Wyoming, I think I have but I am not positive.
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.
