Garage Days was cool, but for a different reason: it introduced me to a new type of music. All my crowd became Misfits fans after that cassette came out.
I saw the Master of Puppets tour, with Metal Church opening, in late '86. To my eternal regret, this was just after they returned to the road after the death of Cliff Burton.
I did mushrooms at some point that night and I also bought a Ride the Lightning shirt with a glow in the dark skeleton. We ended up at a party at some stranger's apartment and I ended up standing in the dark bathroom staring at my shirt in the mirror for a long time. It was a good night.
