Gas lines were building again Friday in the New York area ahead
of the blizzard due to hit the region later Friday.  "The line
for the River Edge BP is backed up to New Milford ," tweeted
Brelyn Kirk, referring to two neighboring towns in northern New
Jersey.  But experts say it's a result of panic buying caused by
bad memories of Superstorm Sandy rather than any likely gas
shortages.  Many lines were stretching for blocks again, and
there were some gas stations that were running out of gas,
particularly in New Jersey on New York's Long Island, where
prolonged power outages following Sandy made gas a difficult-to-
find commodity for a couple of weeks.     Tom Kloza, chief oil
analyst at the Oil Price Information Service, said the storm is
actually likely to create excess supplies of gas in the affected
area by keeping people off the roads and thus suppressing
demand. But he said the memories of the last storm is probably
causing more topping-off than usual, and some short-term
shortages.
