Oxbow Bend along the Snake River was also an excellent place to view wildlife - we got to see a coyote, a few bald eagles, ducks and swans, pelicans and beavers!
I had lots of fun with my Grad ND filters, although its difficult to guage the placement of the graduation without a DOF preview button. Sometimes I'm not even sure if its working or not. Also, I think I'm getting some nasty magenta color cast with one of my ND and the ReverseND filter. Have to verify and send back for replacement if that is the case. (However, I'm not sure if that is entirely a bad thing because the skies get a warmer color temp - which works well for sunrise/sunset)
