Monsanto park sits on the former site of the Ellington Plantation in Lulling, LA.
Ellington Plantation was built in the late 1850s to the design of the younger Charles Gallier by Francois Mayronne, who had bought it from the State of Louisiana on May 9, 1855 for $115,000.
The cache is small bison tube. Should be a quick park and grab!
