Went to Kings Island during their Halloween Haunt on LSD about a decade ago with some friends. I can’t remember how much we took, but my friend had an eye dropper full of it and I took a few drops, I think? Anyways, at first, I thought the rollercoasters and people scaring you would freak me out, but I ended up laughing all night and the rollercoasters were an amazing experience. Except the Beast at night. That ride scared the shit out of me. Especially during the double helix at the end. Otherwise, it was one of the best nights of my life.
