Reading along in the Sustainable Industries Website [1] I found this link for the earthnow EXPO [2].
It seems to me that plenty of deals are made in Las Vegas that seem to turn up here in NEO. So I'd like to suggest that instead of going to Las Vegas to engage with sprawlcenter bigbox developers, "leaders in Cleveland" visit Las Vegas to catch up in the newest trend - the earth.
At the same time, the Las Vegas Convention Center could be explored (you guys may know it like the back of your hand). While I would rarely advocate going to Las Vegas and have little interest in the place myself since it seems to be a mecca for what I might consider wasteful and frivolous, this time there might be a payoff for our region should someone from Cleveland venture out there in early June 08.
C'mon Cleveland+... let's get up to speed.
