Frank, Rob and I meet guide Brian Peace ("Bowcrow") for breakfast in Calgary; we cross the Bow on the new Deerfoot Extension bridge, and put in at Policeman's at about 10:00 a.m. I'm interested in learning Brian's "winter" nymphing techniques, and he is happy to oblige. Note to self: for sheer numbers of good rainbows, it appears that the March-April timeframe can be prime - see Bowcrow's website for example. We fish the runs at Policeman's, Must be Nice, the Cliffs Of Doom, and the Cliffs Of Insanity with pretty steady action, mostly on SJW rig, some on streamers. Bowcrow's preferred setup is an 8 wt. rod, with, i.e. a #4 SJW, a Prince, etc., then a bigger San Juan on the bottom. All on Berkley 8 lb. test for tippet, 14 lb. for the leader, and a strike indicator about thumb size. You are to aggressively mend upstream just as the line is hitting the water, and strike HARD at any bobbing of the indicator. "Combat"-style fishing, and hard on the arm but it undoubtedly works. Frank has a leak in his waders and a saltwater line on his reel, not so good in cold water. Rob gets a bunch of fish today.
