“To James Hoban, architect,

I have included in this letter details for upgraded features for the Executive Mansion.  The escape tunnels may become useful should a future president need them.

-James Madison 1815

*I will preserve the original façade! H.S. Truman

**I love the escape tunnels! G.W. Bush”

I’m not seeing any upgrades nor escape tunnels. One of the maps has a small handwritten note on it though. “Use this map in the event of a Fire”. -Veritas
