Sheltieguy - I certainly respect your opinion of zoos and sympathize.... but...
you are in NE PA.
I would seriously urge you, when the weather turns, to visit the Bronx Zoo. On a Sunday I drive down from RI, spend 5 hours and drive back and it makes a nice day. Little traffic or hassles on a Sunday. You are what - 2 hours away if that?
Check out the Gorilla habitat, the Southeast Asia building, the African Plains. See all that zoos are doing for conservation, research and most importantly education, particularly of young people, about preserving habitats.
. Watch 'enrichment time' for the Siberian tigers, (and gawd they are beautiful watching them play from 10 feet away,) the bird house.
You can see the care and compassion in every word the keepers say.
Zoos are no longer a tiger pacing in a concrete pen.
Seriously, i don't mean this as an argument, but rather a suggestion. Take a Sunday, check out the Bronx Zoo. Its a great experience and probably an eye-opener. - Dr. Mac
