Regular rain coat, because I love photography and cameras are hard to use with an umbrella. Have one as a backup though. (though admittedly I just had fun tracking the umbrella down after it fell off my camera bag in middle of nowhere. Found it hanging off a tree fortunately) My current jackets can handle light drizzle.
Also, proper rubber boots which I’ve been using for, uh, can’t remember, at least the entirety of the current millennium. (Indestructible. Literally made by Nokia.)
Side note, but:
I’m studying French but I don’t speak it that well yet.
Oh wait:
I feel like I’m learning important day to day phrases here! Why don’t they cover this stuff in language courses in this day and age, I wonder?
