Interesting Environment

Although this was a project in my class, I decided not looking at it as an ASSIGNMENT but as an adventure. So lets picture this together: I am coming home from work tired and hungry, everywhere is completely white from snow. I am driving toward the hill that we live on and all the sudden I can't control my car and BAM my car ends up on a curb!! I'm stuck...I was waiting in my car for help when I started wondering why snow is slippery when rain is not? or if rain becomes snow when it's cold then why snow is puffy?!
Questions after questions came to my mind and without recognizing  I was doing what I was supposed to do for my assignment.  Among all the questions that I came up with one of them made me so curious and I think I found few decent answers for them. I'm astronomy lover so no wonder why I worked on this question: Why there are more stars in Arizona or Nevada's skies than Washington or Oregon's skies?! Why there are more stars in some areas more than the other areas? after thinking and remembering some basic sceince from elementry school I came up with answers like:
In places with more pollution is harder to see stars because of the smog in the air so for instance it is harder to see stars in downtown Seattle than Redmond.
Also in places with a lot of lights you cannot see as many stars as you can see in a place out of town with no light
And last but not least we can see more stars in Arizona's sky than Washington's sky because of clouds!!! clouds cover the sky and stars don't have really strong light to go through the clouds that's why in Washington we do not have a lot of stars! :(
Alright now that we discussed my answers, let's see what scientifics or I should say astronauts think about this question:
The best places to stargaze are away from big cities and towns because the light "pollution" from streetlights, advertising, factories, stores and homes makes it harder to see the night sky. The very best places are at higher altitudes and in drier climates, places with less moisture and fewer particles in the air.
It was surprising to find out the biggest obstacle for stargazing is light pollution and of course air pollution has its effects too but it is not as big deal as light pollution!

So if you are interested in stargazing like me, here are top five places for stargazing:
1. Lake Tahoe, California/Nevada
2. Haleakala National Park, Maui
3. Big Bend National Park, Texas
4. Jester Park, Polk City, Iowa

5. Mather Point, Grand Canyon South Rim, Arizona

Have Fun and Thanks for your time!
