Our tour started at the Frontier's paint shop. The carpenters all knew Sonny, so we ended up chatting for awhile.The rumour had it that the tunnel had an entrance in an old hallway and down some stairs.

I went to the hallway and down the old rotten stairs. It went to a musty, wet hallway that dead ended. The hallway was only 20 feet deep. If there was an entrance there at one time, I couldn't guess where it would be.

Next, we went to room 160.
Room 160 was a parlor where the show people used to hang and party.
The rumour was there was an entrance to the tunnel somewhere under some blocks, but I kind of doubted it. The room was in the back of the hotel.
It was a really cool old room though.
It had a jacuzzi, nice bath, 2 bars, and full windows and sliding glass doors that surrounded it. I found a 1990 phone book that was pretty interesting, and a dead cat, but we found no tunnel.

The last of the Howard Hughs tunnels may never be found.
What may have been miles of tunnels under Las Vegas Boulevard will be buried soon. They'll be a time capsule, that will be forever lost in time.
I did get a black jack table layout
It was pretty cool seeing the guts of an old hotel.
