If you are in a subdivision with no park, and there are several kids near the same age group within several houses, the street is the simplest play area. It's all I did growing up. A single football could keep us going for an entire Saturday practically dawn to dusk. Bikes and Baseball too. We of course always watched for cars, and we as KIDS were aware of the danger. Speed bumps don't fix anything permanently, because people just race between each one like it's a timed event and they try and go around one side or the other to keep 2 tires from hitting it so they can go that much faster over the bump. Emergency responders (as I understand it) have a tough time with speed bumps as well.
I think the biggest problem we have today, as far as this topic goes, is unaware DRIVERS. So many times on Saturday (we see it all the time), we saw vehicles slowly leave their lane and drift slightly into the next. Even had one SUV do that for a brief moment into our oncoming lane on 455. What were they all doing? Looking straight down at their phones. Most with family or friends in their own cars! Not to mention the hyper speed pace we all seem to get caught up in. So if we're not racing from place to place we can't seem to get everything done.
I regularly have 40mph folks in front of our house every single day. If Anna PD wants to curb some danger and make some ticket revenue, PM me and I will let you know my exact location. I believe the speed limit is 15mph and there are TONS of kids in the streets here when the weather is good.
