Yes.
Bad snow storm on December 22nd 2010 into December 23rd 2010. That Saturday before Christmas. There was a state of emergency, and we had like 18" of snow on the ground that day, and I couldn't drive my van down there, or my Cobalt SS I had at the time. The lady from the catering company was worried I wasn't coming down...I wasn't, but told her I believe my sister could do the job. It took me over 5 hours just to get home from Northern VA the night before! Luckily, my sister with her 4x4 Explorer was willing to drive down. She lived closer than I do. It took her 1.75 hours to get to this house down in Great Falls, VA for their holiday party. They were rich people, and not thinking about the weather. My sister had to set up outside on their 2nd level deck. They had a heater out there, but it was still frigid. Load in was awful, and the drive way to the house was barely plowed as it was still snowing as the party was starting. Only about 30 people showed up to the house party that originally was supposed to have 80. The caterer and her both said it was the worst event they had done. It should have been cancelled.
Only time I ever couldn't do an event.
