<p>hornetguy, What about the Davis Mountains or the Hill County? They are in Texas and are not very flat. But I agree they are not close to Houston. The following is true. A Houston area high school football team near where I live uses the concrete apron between the frontage road and an interstate overpass across the road from their school to run up to do their wind sprints. As it is close to 45 degrees, it would rival any hill at West Point (only not as tall). Where there is a will, there is a way.</p>
