I placed this shortly after the Memorial Weekend flood of 2015. This was a record flood that destroyed homes and upset lives from Blanco to Houston and beyond. The nearby bridge had only recently been completely renovated; the flood waters destroyed it.
The grass here can be tall so watch for snakes and other critters. In the hot summer months, this is a starting point for several local tubing outfits. Muggles are likely to be close during these times. Otherwise, this is usually a light-traffic road and there is a nice spot to pull off and "read historical markers" (I'll know what you're really up to).
Happy caching!
