Does wisteria come in yellow?

Where: Church garden across the street (NYC)
When: May 2011

Because this looked like a yellow version of a wisteria, but I'm not sure that that exists.

Bad back day today - no sharp, crippling pain, but a lot of continuously sharp and nagging pain made doing just about everything difficult, and made me feel extra cranky. Swimming was lovely, in that I didn't have any pain while I did it, but it didn't really help beyond that. I think this is weather related - it's been pouring rain for a couple of days, and I've noticed that rain seems to make it worse.
