Can I really fry an egg on the sidewalk in Phoenix? (If you arrived at this page from search, you might want to start from the beginning.)

Early in the day I started tracking the temperature. The thermometer is inside the mailbox and the probe is on the ground in the street. OK, I know. I'm already confusing the premise because the question is, can you fry an egg on the sidewalk, not in the street. Here's the thing. There are no sidewalks in my neighborhood! The way I figure it, if we have to walk in the street we can try frying an egg on the street.

It's my experiment, and I can do it my way!
