at my university? probably hide out in my dorm. its a pretty secure place and being 7 floors up is convenient.
back home? honestly i'd just chill in my house. its a small town with less than 2000 people and its pretty much crime free. most people would go to the huge city 10 miles away if they wanted to experience some action or loot some stores. it also helps that im in a somewhat isolated middle class suburb not directly adjacent to the highway.
The problem with the purge is that come the next day, you have to live with yourself and the people you wronged.
Do someone wrong enough and it doesn't matter that theyll be arrested for it afterwards, theyll still go after you.
