Petrified Castles

While I was pulling weeds, Grandpa and Cole were working on a new project...

They started with a hollow tube...drilled holes in it

One of Art's loves is rocks...

He finds them..

Collects them...

Polishes them....

Saves them.....

He has boxes and boxes of polished rocks.

One of Art's other loves is caulking...

So he decided to put the caulking and rocks to good use by putting them together....

The result, rock bird houses....

These turned out so unique..

Hopefully a little birdy will make a home in one of these castles.
