HOLLAND, MI (WHTC) - Gas prices have slid nearly half a dollar in the past two weeks along the Lakeshore, as this morning’s survey of Holland area stations showed a per-gallon average of $3.31, the lowest since mid-February. Rates ranged from $3.25 to $3.39. While rate hikes for the upcoming Independence Day holiday are expected, motorists are still hoping to pay less for fuel now than they did a year ago, when petrol was going for $3.72.
