Wind blow dish down, go boom.
Apparently we didn't tighten the bolts enough, and last night we had our first rain of the season. ``What do we need lightning arrestors for?'' we said. ``When's the last time you saw lightning in San Francisco?''
So, we waited until this afternoon to send Bishop down the pipe to re-align the dish, since he didn't want to brave the roof in 70+MPH winds last night. Sissy.
