Our sister-in-law, Marian, was the first to use the Contact section for feedback. She corrected my mistaken description of how the roads are named & numbered in Arizona. Here's what she said:
You talked about the numbered avenues and streets, and I thought I would correct your logical assumption about how they worked. Actually, all the numbered avenues and streets run N-S. Avenues are west of Phoenix and Streets are east. So if you're driving east, the avenue numbers decrease until you get to Central, which is where downtown Phoenix is. Central would be 0. Then you start with streets, increasing in number as you continue east. I'm not sure how far/high they go in that direction, but I've seen at least 135th St.
The correction isn't so important. We're just really excited that someone used the Contact section.
