If you live East of the Rockies, sidewinders or prevalent. West, worm
drives rule the roost.


And the only reason that those on the east side of the Rockies use the
predominately left bladed sidewinder is because they want to have al least
on foot on the shore side of the cliff when they cut too deep and whack off
the west side of California. :~)
