For the past week I've been taking FrontRunner into Ogden, and then a bus to work. With gas approaching $4 a gallon, combined with Flying J providing an Eco-pass, it saves quite a bit in gas. My car is still three quarters full a week and a half after filling up. It does take an hour to get into work as opposed to twenty minutes driving. Paying $65 to fill the tank makes the longer time worth it.
