I once left a nice rod and reel at a boat ramp. Went back a couple days later and someone had put up a sign with their phone number on it saying they'd found a rod and reel. I called and described it and they met me to give it back.
Bull creek fishes well upstream from 360 along Spicewood Springs road. And from the trail head at the base of Scotland Wells about a 1/4 upstream is a spillway that holds some 5lbs. bass but they're real bashful.
