Apparently Peter is unaware that Weishampel was video taped blowing in 
a 2 inch diameter PVC pipe - hardly small and considerably greater 
diameter than Weishampel's trachea. To reiterate, the model of 
Parasaurolophus trumpeting is interesting and fun, but most certainly 
flawed and far from reality.
