Three mayors walk into an elevator – but what happened next was no joke, though the officials managed to amuse themselves until they could be rescued about 40 minutes later.  Leetsdale Mayor Pete Poninski got stuck in the Westin Hotel elevator last night along with the mayors of Pittsburgh (Bill Peduto) and Millvale. They had been attending a meeting of the Allegheny League of Municipalities. Poninski tells Beaver County Radio newsman Pat Septak that none of the mayors could get cellphone service but luckily, one of the stranded passengers worked at the hotel and was able to summon maintenance crews and first responders using a walkie-talkie. Poninski says that while the mayors couldn’t call for help, they did manage to use their phones to take a selfie.
