Black Friday is the biggest and busiest shopping day of the year.  It occurs on the Friday after Thanksgiving. All the stores are having some of their biggest sales of the year. Many of the stores open up early on Thursday nights and seem to be opening up earlier and earlier each year. The sales follow through all day Friday. People line up their cars outside of stores and over fill parking lots and sometimes have to park in other free spaces by stores because of all the people out shopping this day.  Some people camp out outside of stores to be sure that they get what they want before the store runs out of those products. Black Friday can sometimes be dangerous. Because of the massive amount of people out shopping there is a big risk of car wrecks and accidents. Some people get into physical fights over the different sale items which results in having the cops and sometimes ambulance called. In case of an emergency like this, with all these cars and people everywhere it makes it hard for the ambulances and cop cars to get, which could be very bad if something were to really happen.
