Solar and Pulled Pork

This is one of our existing gas lamps, photo taken same time as that of solar lamp from yesterday's post.
Last night's (or more correctly early this morning's) review by a friend suggests that the level of illumination provided by the solar lamp was less than that of the gas lamp (or at least insufficient) after it was run for 7 or 10 hours.
Perhaps an adjustment will correct that perception or we may consider additional lamps to compensate. Additional lamps may still be cost effective yet will require a longer amortization period. We shall investigate and report.
NOW TO PULLED PORK
http://lasvegasidiot.com/ provides us with a sign which depicts an advertisement for "pulled pork sandwich..." One usually associates "pulled" with ropes, rail freight cars, horse drawn buggies and similar. Why "pulled pork?" L.E. is not aware of the existence of "pulled cow" (again, other than by rope and definitely not a sandwich). Also L.E. is unaware of"pulled fish," or "pulled chicken," other than a pullet. Why are these animals being discriminated against? Why can only pigs be "pulled."
