    Now for a quick plug from the tourist bureau - CANADA - specifically NORTHERN Canada in the winter - come for the polar bears, stay for the 13 to 15 hours of dark skies EVERY night. The only thing that can screw this up is the Aurora, and if it is active, you will definitely want to add that experience to your bucket list, so as Bob Barker said, "Come on down!".
    That is true. Communities are working to reduce ambient light being projected skyward. Light transmitted away from the area intended to be lit wastes energy and produces a myriad of other issues to wildlife and human health.
    I've attended several seminars in my area concerning light pollution. Several communities in the area have passed lighting regulations. Enforcing these ordinances is another issue. However, bringing awareness of the issue is a good beginning.

    I was looking at a light pollution map and there a lot off places in the USA with some nice dark skies! When i'm in the states later on this year i might have to visit some off these beautiful places. I'm currently talking to some Western Australian government officials here in Perth about having one night a year where the lights are turned down where possible and arranging local Astronomy clubs to have star parties so ppl can see the milky way. I might call it bring back the night or something like that!

    Had the fine pleasure of visiting the Grand Canyon last November and stayed in Flagstaff AZ for a star party at an observatory. No moon and was a great experience, much better from my views on the Northeast USA. I happen to be in St. John this week and the Stars are impressive. Able to see the southern cross, which is kinda neat, but I must say to the north on the direction of St Thomas, the light pollution is horrible. To many dam lights!

    Great video, BTW. Thanks for sharing. I always turn off my lights and sometimes my neighbor's too, with a gentle twist of the wrist on their outside bulbs. But please don't tell anyone. :-)

    It helps us here in Socal to live near Palomar. The city is always checking with the atronomers when making lighting decisions. It's still bad in San Diego, but Escondido isn't as bad. I'm borderline red/orange and live about 1-2 miles from the city center. I did manage to see hints of the Milky Way last year from my yard. I think if I didn't know it was there, I probably wouldn't have noticed it.

    I'm about an hour from much darker skies (San Diego Astronomy Association's dark site in Boulevard CA). I'm also fairly close to southern Utah (about a 6 hour drive) for a weekend trip. Very nice skies out there near Bryce Canyon and it makes for a beautiful day trip.
