I continually have been picking up good colored purple/plum Cal signals when i see them while trying to find the darkest I can. After 12 years, the 161 in this pic is the darkest i have been able to find. I have seen very, very few 162's here on the east coast and at the recent Shrewsbury show got the one in the pic. It is the darkest Cal signal I personally have seen to date. Now if only the beehives were this dark!
