Dave -
While not pink the first time I caught a steelhead on a "rubber worm" was at the mouth of the Tolt in July of 1963 or 64. It was on a "Creme de Long" rubber night crawler. Those that came pre-rigged with 3 small hooks, a couple beads, and a little airplane spinner. The summer runs loved them and would come running from a long distance to gobble the "worms". The playing of the fish was a little tricky due to the small hooks.
