Just northeast of ya'll (5 hours), but had to say hello and share.
Was in the Austin area last week and made plans to stop and visit
the "slab" on the Llano, just outside Kingsland on the way home.
Way cool area!! Only had enough time to spend one day, but brought
both water and land MDs. Found alot of trash (can slaw, bottle tops,
pull tabs) but did manage to find some clad, but no jewelry. Met a
couple from minnesota that were down south on vacation; panning
for some color.....don't think he ever found any.
Good luck on your next adventure!!
