Ok, well, Kirt got back to me.
He says any weekend after Thanksgiving and before mid-December is fine. He says that he's open to us having a plant trade there, and I think it'd be nice if we could donate him a generous portion of plants either for his store or for his home tank. I'll ask him what plants are on his "wanted" list. =)
He's already planing on setting up an ADA tank at his store, so I don't know if we'll be able to do the scaping idea.
Anyone else have suggestions?
