Cliffside - Cabin 2, 1947
Top - "Poodle" Hayes
Right - Bob Grim
If you look closely next to the right sleeve of Bob Grim, (ok, ok it's his left sleeve -- to your right!) you will see the small drilled hole in the window sill.
This was on each cabin, and after inspection each morning, an american flag was placed on the winning cabins in each group.
(In the 50s, the groups were cabins 1-6 and 7-12)
