This is what they look like in bloom, and here's a good article about the native vs. non-native lupine species in Maine: https://www.nps.gov/articles/000/lupine.htm#:~:text=This%20plant%20is%20not%20native,to%20as%20an%20invasive%20species.

What does the listing say? I think you probably could, but there’s a ton of boat traffic through there in the summer, so it might not be particular safe. The channel is pretty narrow, especially near the mouth.

It isn’t just Maine, either, but most small town and rural areas in New England. We never used the front door in my parents’ house in MA except to move furniture because it led directly into the living room and stairs and there was no place to hang coats/remove wet shoes. In my current house in Maine, we actually do use the front door as the main entry, and have a gravel path directly from the driveway but it still feels a little weird to me!

Wow, thanks for pointing that out! We got heat pumps last year, and using the calculator with our usage data from last year, we would save $400/year.
