As a child, I remember seeing these cheesy commercials with a catchy theme song for Tri-City Sporting Goods in Fremont. I still occasionally see them now, late at night, or in the middle of the day, if I'm home from work and watching TV.
They used to have two buildings -- one full of sporting goods, and another full of patio furniture. But they recently tore down the patio furniture building, and have now moved the selection over the other building. They carry everything form clothing and shoes, to snowboarding and skiing gear (including rentals), a bike department, workout gear, and other sporting equipment (e.g. baseball, basketball, football).
Despite having a very good selection, their prices tend to run higher than most other stores in the area. So, if you can find the same product elsewhere, it's likely to be much cheaper. But, sometimes they carry things you won't find so easily in other local stores, so it may be worth checking out.
