Wondering where to treasure hunt in Texas and/or the Ozarks

[TreasureHuntingPug]

My family is going to go on a vacation in a couple months, but we don’t know where we are going yet. Most likely, we are going either to Texas or visit the Ozarks in Missouri. While it’s still months away, I’m doing research to see if there are any spots to treasure hunt. I am wondering if anyone knows where to treasure hunt in those places.
