Hey Bob,
What great work! I haven't been to RiNO, though I have seen photos of it. This is a great reminder that I need to get down there on one of my trips when I am at my daughters.
The first 2 are my favorites as I think people in Street Photography really adds to the images. I like #3 and 4 as well, but #1 and 2 really stand out, and I like how you worked the DOF in #2. Very clever work there as it had just enough DOF that we can still make out a person walking away.
