I collect rock's for a hobby i get some more than three times a year a year from my nana,granpa,granpa smith,and my dad.Now i have over 50 of them in all shapes and sizes.My biggest one from 4 years ago is a stone sea shell from when my dad was Turkey hunting in the mountains. He saw a hole reef of Star fish,Corral,fish,Sea horses,and sea shell's.but all my dad could get was that sea shell i have and it still remain's my favorite.
