Clay I get what you are saying but in these crazy times, >Aug 2009 (and YES this was part of the beginning of these crazy times) all bets are off. Remember, words have meanings and meanings have definitions and in CA a suction dredge is defined as " the use of a mechanized or motorized system for removing or assisting in the removal of, or the processing of, material from the bed, bank, or channel of a river, stream, or lake in order to recover minerals."......... a highbanker is a motorized system.. While not included by name it is included by definition.
That is from the state legislators (stop calling them law makers,,,,,, it only encourages them) That is the basis the guy in the smokey the bear hat will use when he says "press hard there are 3 copies"
