After spending hours on the web looking for stone quarries, I've decided to inquire from those of you in the surrounding areas where I might be able to find irregular shaped colonial grey flagstone, approximately 2'x3' or 3'x4' in size and about 2-3 tons. Even if you know of a nursery selling what I'm looking for, I'd appreciate their recommendation too.
Thanks sandykk, for recommending All Landscape Supply. The guys were most knowledgeable and accommodating. When we presented them with a small piece of the 3'x4'x3-4" sized 75+ year old stone we're working with they immediately identified our problem in finding similar colored stone. They offered several options and a couple of referrals. Again, thank you.
