Unplug your internet when testing....
Please note there are limits to the free account: 10 queries per minute, and 500 queries per day.
IMPORTANT: Each Weather reading takes 2 queries!! (One to obtain City info and another to obtain the weather for the city) - so you can check 5 locations in 1 minute, then wait another minute and check another 5 (up to 250 readings in 1 day).
That means you started RR 250 times a day.
