RE: how long til meat spoils.
your in maine?? whats your high temp for the day???
likely not much higher than 58 that it is now???
if not much higher than 60 or so(i may even go to 70) i would say it will be fine with ice in it and in the shade.
overnight, the low would likely been low enough to not matter....
i wouldnt suggest waitin ALL day but an extra few hours with it being kept full of ice, and out of the sun, id say it would be alright
