I love being inside on a rainy day. It's awesome to see the huge flash of lightning and knowing that a giant bomb of a thunderclap will be coming in a few seconds after the sound catches up with the light.
If you count the seconds, you can estimate how far away the lightning was if you know the speed of sound.
I think everybody in Calgary heard that one huge thunderclap. I was playing the Thunderstruck intro on my guitar at the moment too
