You are right, Gary. I wasn't trying to flame you, but rather educate the ifish community in general.
Certainly it is good to know you aren't intending to be a hole hog or worse, unsafe in your anchor spots.
Another place for two anchors is in the Willamette. I use a pyramid if I anchor anywhere above the old OC bridge to the falls. That area is a spot to almost guarntee loss of a rocker anchor, because the tines tend to get caught in the crags of the rocky bottom and even if the safety ties pull loose the anchor still doesn't.
Another good choice for areas like that is a big bunch of chain, since it will lay in the bunch and pull right up. If you have a good source for that you can gather it into a ball and use it. It still would require about 30 pounds plus though to be effective.
But, anything below the old OC bridge, as well as anywhere on the 'Lumbo, you want the rocker and a bit of chain to dig in to the soft bottom,
In any case, you want a couple anchors anyway for when you choose to go tidewater fishing down at the coast. An anchor off each end keeps the boat in place.
Hope this helps!
