As far as I know Patio is still around. Rainbow Jersey moved to Santa Monica in Shorewood and recently got bought out by Erics. Brent Emery still on 99 & Capitol, just in there the other day & in Menomonee Falls. He does a lot of good stuff in the adaptive community. W & S is the 800# gorilla in the market with like 10 locations in SE WI & Fox Valley. They have used stuff at the Hales Corners Store and do lots of charity ride support and advocacy. But yeah, too big and impersonal for my taste. I prefer Ben's but actually patronize numerous shops depending on where I'm traveling or if they have it. There are actually quite a few shops in MKE, probably more than you would expect for a city this size.
