It’s fine to ask a question like this, but you don’t seem to be accepting the advice you’re receiving - from actual people who live in DC - that your fears are overblown. I lived in Adams Morgan for 8 years and I was never a victim of violent crime. Go to your convention or don’t, it doesn’t matter to me, but if you ask for advice, be prepared to receive it. Otherwise just stay in Indiana and live out your years there, without having seen your own country, let alone the world.
