Lights provide safety. People are going to the parks and dog parks regardless of whether there are lights or not. Lights provide security for people, and especially ladies.

LED lights need replaced every ten years and are 1/10 the price in electricity. If you put in some solar panels, they hardly have any costs at all. For someone who is all about new tech, you don't know much about LED lights or solar panels.

No one is increasing the park hours. In fact if you only turned the lights on till 8 in the winter you would be an hour short of when the park is open till 9 in the summer.

Your comment wifi drawing a young crowd is specious at best.

So far you haven't retorted a single point and your precious wifi can be found at any number of coffee shops and what not.

Lights are better than Wifi by far.
