need quotes about overland adventure


I am giving an informative speech in class about overland adventure.
the four points are

Vehicle preparation
Techincal Trail Navigation
Vehicle Recovery
Post Vehicle assment/fabrication (what do i need to make it better)

I need some quotes of stuff that people have said on the trail and who said it... please try to get it as a quote because I am suppose to have two 'expert' quotes in the speech.
