I saw this article about putting a quarter on a cup of ice before leaving for vacation. Cool tips on checking for power outage when returning from a trip. hope the link works.
Checking for power outage
We'd know if there had been an outage by looking at the clock on the coffee maker and microwave oven, but the coin trick is another good idea.
Yes, sometimes our TV and lights over the kitchen counter top stay on to alert us. Better predictors are our oven and microwave clocks.
I read the article and there are some excellent ideas for all of us. Just a couple of days ago a brief power outage happened while I was on the computer. Very few other neighbors noticed until lights or clocks were awry.
During summer months in FL, we get plenty of lightening strikes after all we are the lightening capitol of the world.
Thanks for posting the article. It will helps lots of "mates." Although TVs, lights & clocks tell us there has been a disruption of power, they don't tell us for how long.
