My neighborhood is always being canvassed by Mormon missionaries.......They ride bikes and wear helmets......no antlers though.......
That was the one thing that was hard to get used to as a missionary was having to wear a helmet while in a suit. Riding the bike wasn't that bad, but the helmet just bugged me. But it was the rules. We had to keep safe.
I think if the helmets had antlers, I would have WANTED to wear it. That would have been cool.
I have known plenty of sister missionaries (female missionaries) who had the disposition of a cantankerous moose though.
