AUBURN, Ala. – Come back in an hour and a half, Michael Garber says, because that’s when his tiger-striped party bus will actually be properly assembled, lit up and ready for friends to drink inside (and around) and passersby to gawk at. It’s about 8 p.m. the night before Auburn’s season-opener against Washington State (4 p.m. PDT, ESPNU), and Garber and a few of his pals – he answers his phone and confirms several more are on their way – are preparing the bus, nicknamed the “Tiger Prowler,” for a night (and day) of tailgating.
