I'm living in Lubbock, and am looking for new bike trails to go try out. The only ones I've been on are Buffalo Springs Lake (twice), and JFK/Mae Simmons Bike Trail (twice a week). I've heard of a trail locals call Purina Mills, but don't know where it is. Also, I know there are trails at Palo Duro, but I haven't checked them out yet. Directions and/or reviews would be great.
