Anyway, I think I speak for most Cascadians in saying that we do not support replacing Cascadian currency and the Sasquatch twig-pegged barter system with the SPP's Amero, which will undoubtedly be even more psychotronically laced than US and EU coinage.
As to immigration, Cascadia has been enriched by people of many different cultures who have contributed to Cascadian society. Whether software engineers from around the world coming to work at Microsoft or Yeti arriving on Cascadian shores hidden in cargo containers, they all dream of the prosperity and freedom that we Cascadians enjoy.
However, I think you will be glad to hear that the Sasquatch Militia has a plan to build a ten-meter-high log wall around the Cascadian border to keep illegal Americans, Canadians, cryptozoologists, and other assorted trouble makers out. At about 300,000 twigs per log, it may take a while for them to find the necessary funding in their budget, although a proposed tax on psychoactive lichens should make a large dent.
