I wish I could, but my car is under the weather again, and I live too far from anyone to hitch a ride...I was planning on going next weekend if my car is fixed, and dragging my girlfriend along for the ride

If you end up going, could you look for some granite-type rock for me? (Not to buy, just to see what they have.) I'm planning on replacing the slate in my 30gal, as I think it looks unnatural and weird. Thanks!!
