There is just something about “going places you’re not supposed to go.”
My twin brother and I once tried to infiltrate the steam tunnels under BYU. It has been done many times, but we didn’t know where they entrances were. We found one possible entrance, but for some reason—I think it was the fact that that particular tunnel was about 200 degrees— we decided not to go in.
I am currently exploring cities all over the world from the 70 degree comfort of my favorite chair in my living room via The Urban Exploration Ring “This ring contains sites focussing on the art of urban exploration: touring storm drains, abandoned buildings, rooftops, transit tunnels, college steam tunnels and other off-limits locations.”
