The three-day Natural Gas Vehicle Expo at the Charleston Civic Center features “big” attractions, including a private concert by Landau Engene Murphy on Monday, but nothing is bigger than the propane-fueled Blue Bird School Bus on display in the exhibit hall. Jeff Pschirer, vice president of school bus sales for Blue Bird, distributed information on the school bus. The expo has attracted representatives of national gas industry from around the state and nation to West Virginia. Numerous natural gas-fueled vehicles – trucks, SUVs and even a motorcycle – are on display. The event is hosted by the West Virginia Oil and Natural Gas Association (WVONGA) and Gov.
