Spitz,
We have three BBSs that offer cacti and succulents (sometimes a couple others offer them as well) but they only receive "batches" twice a year. Most times the selection is the same at all the stores and even with the new "batches." Kinda stinks, but I have to be sure I go look right when they get their shipment in because very little has been picked over. I'm more likely to find something unique then.
I did find a 'Grassie Lassie' Aloe hybrid at a local farmer's market last month. I've been told they're pretty common out in Cali, but it was something I'd never seen before. I wasn't aware they carried C&S at this farmer's market lol.
In some ways maybe it's a good thing we don't have places here like you do. I'd be coming home with a car full every two months.
