No, I didn't actually.  I checked it out thoroughly, and it showed no signs of damage - no cracks, compressed liner, separated liner.  All seemed well, so I've just kept using it.  To be honest, I've been a bit skeptical about that assertion to replace the helmet after an impact.  They're a pretty simple construction -- hard shell, expanded polystyrene liner glued into that, foam padding and fabric over that for comfort.  I've never read or heard of a good, solid, technical reason why a helmet needs to be replaced after an impact -- notwithstanding the obvious, that is, as mentioned above -- **** shell, compressed or separated liner.  Motorcycle helmets are an exception, I think, due to the speeds involved -- I replaced one of those when my bike fell over in a parking lot, and my helmet was dangling from the handlebar....the 500 pound bike fell on the helmet and **** the shell.

But, you have given me reason for pause and second thought -- thanks for the reality check.  I will look into this further and see if replacement is justified.  If so, then there's more shopping to be done....groan.....
