Pecan trees in public squares in Texas

Notions Capital writes:

Parks and courthouse squares in Central Texas are planted with pecan trees. Families often picnic and then pick the nuts out of the grass with pole-mounted tin cans.

And I found this from the American Nut Growers Journal from 1921 in discussing pecan trees in Victoria, Texas:

According to JD Mitchell, Sr., entomologist, the pecan trees on the public square which are now quite young, will in a few years produce an abundant supply.

This is from "Treasure Island: Riches of all kinds are well within reach on Seguin-area tour" in Texas Co-op Power Magazine:

Seguin is known as the Pecan Capital of Texas for its pecan-producing industry, and pecan trees abound on the town square, where a pecan-shaped sculpture nearly the size of a Smart Car graces the front lawn of the Guadalupe County Courthouse.

The photo above is from Seguin, Texas and the sculpture is visible in the photo.

Although, as much as I want to plant a pecan tree, you need at least two to get cross-pollination, and according to one Cooperative Extension website, the nuts are subject to many diseases, so they say grow it for shade and if you do get nut production, that's a bonus.
