Running errands can be very taxing on the body if trying to do it in the middle of the big summer heat.
Having the big summer heat around you means only one thing if you want to survive while having to be running errands all day in the hot sun.
And that is to make sure that your car has the best possible central air conditioning that you can get! If you live in a really hot climate like I do, central air conditioning in a car is almost as important as eating meals to survive. Without central air conditioning system use you would surely die in such a climate that is so hot, that they actually have heat warnings to stay in! On those heat warning days I always make sure that I do not have to run any errands. Even with the top of the line and most expensive central heating and air conditioning system that I have in my car, the air conditioning can not combat the awful heat on those days and it is best that you just stay inside. Central air conditioning in my car is something I would rather have before central air conditioning in my home even. As crazy as that sounds, if you are on the go a lot like I am, you will need to have the central air conditioning in your car more than anything. Especially if you have lots to do on those super hot over one hundred degree days that may be ahead for you.
