I’m in Myrtle Beach now and was shark tooth hunting this morning. I got some nice ones including a One inch Great White tooth. Nothing millions of years old...yet.
Look 20 or 30 feet up the hillside in some old tree roots, where no one else bothers to look. That’s where you’ll find the good stuff...
‘Course, take my advice with a grain of salt. I never find anything. I’m lucky if I can find my keys in the morning. :-)
