Poison pen
It may not pay to protest, but you should at least
be able to protest when you have to pay or so thinks
a Duke University taw student. Saul Kerpelman was
scrawling unfavorable comments against the Duke
Power Co. on the back of his monthly utility pay-
ment "to ridicule, express scorn for and encourage
public awareness of . . . unreasonable, unjust and
unfair profit structures" of the company until the
power company filed a complaint against him for
obscenities on mailed items. Undaunted, Kerpelman
has filed suit against the North Carolina U.S. At-
torney and the local postmaster., Whatever happened
to the good old days of folding, spindling and mu-
tilating? May we suggest a protest punched into an
IBM card, the computer may listen.
Jai ffor sale .
.Ever dreat- about life behind bars or thik of

locking someone not so near and dear up for a while?
Well, Lime Springs, Iowa can make alt your dreams
come true. It seems that life is so peaceful and quiet
and it's citizens so law abiding they have no need
for the town jail. "The only thing I can remember
we have used the jail for in the last 17 years is to
sober up the town drunk," says Lenny Peter, mayor
of the town of 500. So, the old place is going up for
sale, City Council will take bids this week. Anybody
having trouble finding a place for fall?
Happenings ...
. . . for the young (ages one to nine), a children's
festival will be held at West Park from 10 a.m. until
2 p.m. today. The fun includes a puppet show, pet-
ting zoo, magician and musicians. That's the extent
of Saturday's good times . . Sunday features only
the opening of the Ann Arbor Art Association's "A
Bit of Whimsy" display, with works by four local
artists including ceramics, batik and fiber works.

The display, at 117 W. Liberty, will be open from
3 p.m. until S and run through August 31 ... Things
get back together Monday with an evening concert
by the University Summer Session Band, Allan Mc-
Murray conducting, 7 p.m. at the School of Music
reflecting pool., Other musical happenings include
the week-long National Choral Showcase at the
School of Music, featuring several workshops and
programs. For information call 764-0593. For those
who plan ahead, an art exhibit by Moyo Roho at
Trotter House will open August 14 at 7:30 p.m.
On the Outside
It will be icky, sticky all weekend as August finally
gets its muggy act together. Expect a cloudy, hot,
humid 85 today with possible thundershowers. Night-
time shouldn't be too bad with the temp in the low
to mid 60's. Sunday will be a re-run of today, but the
sun may pop through a little more. Plan on more
thundershowers and a high of 86.
