So true in this situation. I wouldn't ever try to tell anyone that I have not exceeded the speed limit by this same margin. I can't even say that I haven't done that in the last two weeks. However, life experience will educate you on when it's less risky and less likely to be caught. Going through the park like that is just asking to be picked off. OP has now been educated, and it's going to cost him some money.
