The only time I've caught these guy on an almost constiant basis was around the north Georga Stairt or Salish Ocean. Mostly around 140' to 200' on a sandy bottom, the best spot was around Gorge Harbor but we did catch on in the 20lb range off the light house at Campbell River - it bent the shank of a No. 1 hook. Asided form sparatic encounters and places they are pretty few and far between. However, they catch them in traps on the Deadliest Catch or at least the one boat skipper by Sig does.
have fun, Jason.
