Kenny Chesney show in Pittsburgh goes off with less incident this time.

Although 37 people were hospitalized and seven arrested at Kenny Chesney's Saturday show at Heinz Field in Pittsburgh, city officials say they're "very pleased" with the way things went.  None of the casualties appeared to be serious -- nearly all were for dehydration or too much drinking. The arrests were all for minor booze-related issues; a handful of summonses were issued for marijuana possession. And despite mountains of trash left behind after the show, it had all reportedly been cleaned up by early Sunday morning.
