I haven't been to an event there, nor am I likely to go; cost is prohibitive for me.  <br/><br/>Whether or not it's been a plus for Tulsa so far, I can't say.  I would certainly like for it to make money over the long haul, since the alternative would be for it to turn into a monetary sinkhole.  I'm told that it has made money, but that it's unclear whether that is money the city wouldn't have otherwise had, that is, it may be the same money that would have been spent elsewhere in Tulsa, had the center not been there.  <br/><br/>I do think that--from the outside, at least--it's ugly as sin.  I found "duct tape bowl" quite an appropriate description.
