I thought so as well, I thought however on Bing maps that near the bar you could see a red tent in the image. It might not be but it looked that way to me and it was in the lot next to the bar towards that exit ramp.
I wondered if the burn barrels where close to the tent ,because really it is cold outside and I am not seeing how Nick could stand being out in the cold for 3 months and I really think he didnt only sleep in the tent.
The burn barrels are close to the building's back exit.
