Personal Experience: The Midland Tunnel was discovered one day during a walk, and since I know a handful of you enjoy exploring storm drains I figured I'd put it up here! We didn't make it too far because there were bats inside! Agh! I'm actually intrigued to get up close and personal with them though so next time I am going to have some sort of armor and mask on. 😛 I'm sure it'll be a sight to see. If anyone knows where this ends please let me know!
You don't even need to hop the fence to get in. There's a little slot to enter if you look hard enough:
There's a bonus tunnel to the right of the storm drains that we didn't see from the street!
