Abuse of track

I don't mind the old walkers out there, but Friday there were 5 people abreast walking the track with a dog.  Today, there was an obese woman with her daughter riding bikes on the track.  If I were doing a tempo set of repeats I might say something but just doing a few quality sprints, I just wait til they're out of the way.   Clear violations of track rules that are posted on the gate. 

I may do a tempo set tomorrow.  Cloudy and 60ºs forecast.
