Got invited to fish the famous Lake Arrowhead - a private lake in the San Bernardino Mountains. It's deep (up to 180ft), crystal clear, and has a variety of gamefish (trout, largemouth bass, smallmouth bass, sunfish, and reportedly even kokanee).
Fishing was not easy - I'm not used to fish steep dropoffs right at the shore! Still managed to tie into a smallmouth bass. Had a bunch of little largemouth follow all my lures around, one ended up getting foul hooked, all safely released. Fished spybaits, dropshots, crankbaits, jigs, soft plastics.
Be nice.
