Light Pollution and lack of backyard ranges
Light Pollution Map USA
I grew up in the country of the upper midwest - and I do mean country. 10 miles from a town of 1200 people. I could hear a car approaching from two miles away on a still day. My shooting range was my backyard - 10 acres surrounded by endless wheat fields.
I could look up in the sky and see the Milky Way at night (I had 20/20 vision back then).
Today I live in large metro area. I can see the moon, Venus, and maybe the North Star on a good night. And if I use my backyard for a range, I'll be thrown in jail.
To all you members that live in "the sticks" where you can see the night sky, I want to remind you how good you have it. After the sun goes down on your backyard shooting range, take some time and look at the Milky Way.
