Subject: Re: Power Lines and cows?

Post:

Clarence:

1. Did you 'inhale'? That is, swallow the magnet so that it would
lodge in one (?!) of your stomaches? Would that affect your
perceptions, assuming that you didn't require a Heimlich maneuver?

2. How long did you graze under the high tension lines? Was it a sunny
day or cloudy?

3. Did the magnet heat up due to stray induced currents?

4. Perhaps you should 'borrow' a cow and stake it under the line. Then
record its orientation every five minutes for a few days. Then get some
sleep.

5. Did you spot any rather large flora, or fauna, or sea urchins while
you were under the lines? If so, just how did you dispose of that large
radioactive source you once had at Oakland-- the one that was stored in
the pig/cow barn that was later leveled while you were out of town?
