Haha. We go there all the time. We actually live in Frisco and work in Plano, but head out to our property as much as we can.
Don't wamt to hi-jack your thread - don't know diddly about culverts but know a lot about ponds and fish.
I live in Plano and ponds 20 miles north of Sulpher Springs.
Headed for Highflyer's lake for a quick trip after a bit - he's near Winnsboro - you have many PondBossers nearby.
Cheers,
