Well. Then if you want my advice on the best approach, I'd go to the tunnels and take the same route every day. Map it out in your head and keep drawing it every single day. Each day take a new route a mile in or something.

It'd be useful to have a group only to cover more ground and compare maps. Those tunnels are pretty sprawling otherwise I'd say we might be able to cover them all with one person.

(Then again, he now knew two people who could turn into wolves and probably could cover twice as much ground as the average person.

He's pretty sure it's rude to ask this guy if he has super powers though and so he keeps quiet for now.)
