Dan,
I think it's interesting that the red-sideds that you photograph in your area consistantly have more yellow coming up the sides from the belly and on the side of the face, than the red sideds in my area, around here they are darker and have more black on the lower sides, just a simple minor locatity thing, but I thought you might find it interesting to note the differences from Montana to Iowa.
Good luck with the crow bait red sided, looks pretty bad, but I'm guessing you will be able to pull it off and be able to release it back soon, healed up but scarred, kinda like me i guess, only the snake will still be pretty.
