Somewhere in the GH database are threads with the info about the shop in Berkeley (not too far from LB!) that does custom seats for a Prius. And also a thread explaining why the Camry seat doesn't work in the Prius for reasons that IIRC are possibly design related??

On a side note, check out some of the non-Western ways to treat dis-ease before trying surgery. I visit a chiropractor regularly, massage once a month, watchingmy intake of sugar and caffeine, and drinking lots of water have all made enough of a difference for me that I didn't have to have the surgery that a surgeon recommended for me 20 years ago.
