Has anyone been able to find Southdown or Oldcastle in Houston? I searched about 10 places this weekend and everyone has playsand, but none passed the Vinegar test. I really don't want to spend $40-80 for Argamax sand to switch out my CC if I can help it!
Anyone? I can't believe no one in Houston has found a cheaper way....
there's no cheap argonite play sand in Nebraska either :(
And the beach's like playing with might not get burned at all....or the whole setup could explode from foreign contaminents.

For me, a stable, correct setup was most important, so I spent thd $60 on argamax by Carib sea.
