Oh man Eric, now you tell me! Petlands I've been to only have the oyster shell in with grit; very little oyster shell. I will. John I'll be in Va. and Woodstream in March, maybe I'll find some there. I'm flying to S.C. at the end of Feb. maybe I'll get a little from H.P. Norton then. " Hi Mrs Norton, can you spare a cup of lime?"
