keg question

[Mark L]

my roommate got a keg about 10 days ago (i think it was a thursday). it was a keg that her and some friends got at 130am when they were already tanked, so they barely drank any of it. (lets say its 75% full) at the end of the night they took the tap off of the keg and put it in a fridge thats in the basement. this fridge is basically never opened. now she tells me that if i want it i can have it. this is a $160 keg of a local beer which i happen to love a lot. what are the chances its still any good. im planning on tasting some tomorrow but want to have some sort of idea on what to expect.
