Because of my mom's condition/health, my dad has to take her with in the car. She stays in the car while he runs into Wal-Mart, the bank, the feed store, etc. When I'm there, I always make sure that she has a water bottle--I doubt he thinks of that or I do the get the wheelchair, load her up, park her in a corner, run around, come back and get her thing. I can see how people would leave an elderly person in a car--it is easier than getting the person out, into a wheelchair or snapping the walker open, especially if you're only going in for a few things. But, a car heats up really fast. I have some places I want to stop, but I've had the chickens and Cliff (the dog) in the car, so have not run those errands. Doesn't look like I'll be doing those errands tomorrow or Wednesday either. The errands can wait. It is hot enough in the car when the car is moving and all those bodies are in it. I wouldn't risk a 5-minute stop enroute. Why is it that there are so few trees and shady spots in parking lots?
