Halloween 🎃 for adults?

Do you celebrate Halloween if you have no children? I’ve always loved Halloween and am bitter that it’s not appropriate for a 28 year old with no children to go trick or treating 😩 lol. Also bummed that we live in a rural area so I can’t even make a bad ass haunted house for trick or treaters. So if you have no children do you celebrate Halloween and what do you do to celebrate?
