Whether somebody wears a helmet is certainly their business, but these
helmets are not like wearing an anvil on your head. This idea of neck injury,
caused by the weight of for example the ski helmet I wore this afternoon is
frankly - Utterly ridiculous.

Also the idea that your peripheral vision is affected is also ridiculous. I
rode my bike today on the roads, in and around the NW Suburbs of Chicago,
and had zero issue with that, and I have to check traffic behind me by
looking over my shoulder, and no issue with that either.

That said - Bruce's point about being a proficient pilot makes sense.

If you're flying off sand bars, etc. I'm thinking a helmet might actually be
a good idea ...
