I just got back from an easy 3 mile walk at the local high school.
The school district has actually designated this area of the school as open to the public even during school hours when the teams aren't practicing.
Of course, please keep in mind that just because a track is on government property does not mean that it is open to the public. The proper etiquette is to ask the school officials about it. "But my tax dollars paid for the track!" This argument only goes so far. Your tax dollars also pay for police cars but you don't get to borrow one when your car is in the shop. Please do not use the track if you're told not to.
Halifax County deserves a big "Thank you" from all of us who use this track for our workouts. It is a blessing we never want to take for granted.
