With gas prices climbing many drivers are starting to feel the effects in their wallets.
An expert says the reason is supply and demand. He goes on to say that prices are about the same as they
were in the 1980s once you add in inflation.
�Prices in most commodities are very volatile. Petroleum in 1860 a barrel of crude oil in western Pennsylvania
was selling for $20 a barrel. In 1861 it sold for 10 cents a barrel, so with most commodities there is a
volatility that we're not really used to so much, �William Wilkerson, UVa Associate Professor.
