How about a debate between a Madison University botanist and a Chicago city park district employee?

First discusssion
Daley and his trees.
or
Oehme and Sweden...The New American Garden... do they translate well to gardens beyond the great midwest?

"The great [?] midwest?"

As in the great plains.
But back to the topic, I think there should be a garden talk show where gardeners from all walks of life are brought onstage to talk about gardening from their viewpoint. The first requirement would be an interesting and knowledgeable host.
