Right! My first holiday was like that. I think it's the rule that you have to be puked on at least once in this line of work. By the end, I knew how to strategically position myself and avoid most of the disasters, but the car still took the hits. At least now when my son is sick, I don't run away. Been there done that.
Good luck out there this year. I'm going to try to stay home, but I'm betting I'll be there too.
