Does anyone else ride in a bike helmet? Is their any structural
differences between the two that mean it isn't a good idea to use the bike
helmet? The style of helmet I'm speaking of is a large one with a visor.
It's not just the "lid cap" that I've seen some of the young bikers use,
it's comparable in head-coverage to the Troxel, or maybe larger coverage,
by a bit.
