In a time of increasing obesity and fatter kids, we should be using parks to get people active.  Our kids spend too much time indoors because streets are unwelcoming and overtaken by dangerous vehicles and drivers.<br><br>Most park structures feature metal protrusions to stop skateboarders.  I'd like to propose the opposite: reinforce structures to accommodate skateboarding.  I know this will be controversial, but I'd rather hear kids in the street enjoying themselves on skateboards than cars and trucks.<br>
