I recall what a pleasant thing it was to search the PHYS-L archive
at Prof Hake's urging, which helped turn up a comparable experience
to my acoustic grating 'whistler' experience in a country road.

So now it is my pleasure to offer a reminder of the easily searched
 resource this archive provides.

<http://mailgate.nau.edu/cgi-bin/wa?S1=phys-l>

(Search the archive: use 'canoe' for the keyword.)

"...This problem is interesting. It involves simple mechanics and spatial
 relations. It would make a challenging high school mechanics problem.

 The rig may be seen at http://www.sfu.ca/~palmer/canoe.pdf
