Lol, no! That's based on BU, and was published right around the time I started LARPing. I can't remember if there were tunnels or LARPing in that book, but steam tunnels/walking tunnels are common in the northeast, as is LARPing.
There was definitely both! Man, I should re-read that book. I read it in college, and definitely felt like I was missing out on what I felt should have been a quintessential college experience, like losing a radiation source, fighting off mutant rats, and building my own tank.
