Sorry Tom,
Here in BC, we have bigger fish to fry right now. Thousands of people are displaced from their homes and have no indication of when they will be able to return, and to what they will be returning to!!! Many gas stations are out of gas. Grocery stores are already out of many items like veggies and dairy! All of the major transportation methods and routes are impassable and could be for quite a while with many bridges collapsed! BC has declared a "State of Emergency" and rightly so!
This could end up being the costliest natural diaster in Canadian history, with impacts continuing for a long time to come (not to mention the already problem of "supply chain issues" before the floods), so sorry, we are not right now concerned with future debris that could affect our American friends when they "come north" on the water next spring (even if that does prove to be a bit of an "issue")!!!
Sorry to say it, but I find your post to be insensitive at best!!!
This is not meant as a personal attack, but it is directed at the wording and context of your post.
