Looking for site to hunt in Austin or Liberty Hill area

[PaleoPat 1]

My son and I are going to the Austin/Liberty Hill area this weekend.  Does anyone have any sites they recommend?   It is my first time to the area so I'd appreciate any suggestions.

I have lived in Austin for quite a while, and if there is anything worth seeing, it's a closely guarded secret

Not exactly the same, but if you're looking for somewhat educational weekend fun, you might check out the natural bridge caverns.

Amazing artifacts and fossils around Austin but most is private land.
