The dashboard, door handle, and steering wheel of your car left out in the sun are too hot to touch. The pavement is hot. Sometimes it gets, as the colloquialism goes, hot enough to fry an egg.
Before you take your shoeless kids and dogs outside to race to the car, or feed the birds and squirrels in the parking lot on a 100 degree summer afternoon, or drive a horse and buggy around the town square to give visitors a tour, try removing your own shoes and socks and stand on the heated surface for a few seconds. Well, maybe not that long. Ouch.
We usually wear shoes, so it's easy to forget our companions' feet can blister from contact with the burning paved surfaces around us. This summer, I've seen dogs and horses in pain, and since they are speechless, thought I'd put this into words.
