I'd have a huge "its safe here at my house" sleepover then kill everyone. Then move cities and do the same thing every year while the purge was still active.
It's an idea based on a movie, where literally all crime is legal for quite a few hours (I forget exactly how many) and there is no police/medical help available throughout the whole thing.
Though I'd probably get murdered on the way
Jokes I don't even have my ears pierced. I would probably steal a goldfish.
