| couple miles down. Technically we _also_ didn 't see the
| tornado, but the weather around it was like nothing I've ever
| experienced or want to experience again: continuous multi-
| colored lightning, torrential rain, big hail. (And nothing
| even close to an appropriate building to shelter in.)
|
| Afterward my friend looked a little thoughtful and said "oh,
| I guess I forgot how bad the weather out here gets." Reminded
| me of the way people allegedly got used to the Blitz.

| neighbors outside in the front yard at the same time
| (suburban midwest).
