Areas nearby Wyoming and their current gas price climate:

Fort Collins- $1.94/g, up 7.2 cents per gallon from last week's $1.87/g.

"With the U.S. average price of gas closing in on the $2 level, a price not seen since late December, it reflects a real paradox; we see simultaneously both a stark increase --25 cents per gal. in the past few weeks-- and a reminder of how much we're still saving," said Gregg Laskoski, senior petroleum analyst with GasBuddy. "Even with the anticipated rise in retail prices to accommodate 'summer blend' gasoline regulations, and even with a 54% increase in crude oil from $26 to $40 for the benchmark West Texas Intermediate (WTI), the national average price of gas today remains some 45 cents lower than where we were exactly one year ago."
