	Good old Rolling Rock beer comes in green bottles. It's also
one of the most sensitive to sunlight. It goes skunky in less than one
minute on a real sunny day, so opaque mugs are a must! Their billboard
ads show a Rock bottle in the middle of a bunch of brown bottles and
states "Other beers are brown with envy." Oh well, what do you want from
a small PA brewer? At least they treat their customers good: I wrote them
a letter one time about a spoiled bottle and two weeks later some guy
knocks on my door and hands me a whole case of beer! Not a bad deal.
