This Flag Pole Has Story...

The Tilden Environmental Education Center flag 
pole is a re-purposed mast of "Loon" Bird 
Boat 13, built in 1929. The legendary "S" class 
San Francisco Bird Boats are 30 foot wooden 
sloops that were specifically designed as sturdy 
and affordable craft, able to withstand the 
rigors of sailing on San Francisco Bay. May of 
these classic sailboats are still racing today.
