Places to go to on Halloween!!

hiii, I'm an incoming freshman this year and I'm so excited for Halloween. I know its early to be thinking about it, but I'm 16 and this would be my first Halloween ever and I just wanna be prepared lol (Ik im abit old to trick or treak but im gonna do it for the plot) . I really want to trick or treat but I'm not sure where to go for it. I don't have a car or anything like that but I may be able to get an Uber or smth. And are there any activities on campus for Halloween?
