The only reason I asked was to be curious about the potential for lighting, Many years ago, our County put lighting on a XC Ski Trail. Given how early it gets dark, that was pretty cool. Several years after that, a XC Ski Trail was created in our small town. A XC Ski Club raised funds to have that lighted. In both cases, it was expensive because AC power lines had to be laid underground and mercury vapor lights strategically located on power poles. It was very costly to do.

Now you can get a pair of solar Dusk to Dawn motion lights for about $40!
