"You can't, in Texas, pass a law that's one size fits all," said Bill Grusendorf, a lobbyist with the Texas Rural Schools Coalition. In Harper, a school district of 386 square miles in the Hill Country near Kerrville, bus drivers rack up 300,000 miles per year on regular bus routes. The school district spends $211,368 a year on transportation costs – including bus purchases, fuel, maintenance, driver salaries and insurance – and last year received $196,074 from the state for transportation.
