You thought Shazam was the coolest iPhone app ever in history?
It's pretty neat, but it doesn't come close to Derek Trauger's Bait Shops locator, "an easy to use interface that places an ever growing database of over 10,000 shops at your fingertips."
Next time you need minnows or crawdads, punch in your location. Bait Shops scores your supply like Roland Martin reeling in a smallmouth.
Trauger also has a boat-ramp locator app.
