This article gives the light in which we can observe the reality. This is very nice one and gives in depth information.
So, apparently, all that pretty stuff that peppers the horizon on the outskirts of town is called “the outdoors,” and some folks even consider it great. Indeed, the scenic mountains and desert terrain that surround us aren't just something you learn about when you're camped out on your couch burning through Nat-Geo programs on your Netflix queue. In fact, a lot of people actually choose to camp in them. So now that you city slickers are all caught up on this nature biz, you're ready to rub elbows with those gritty outdoorsy types at the International Sportsmen's Exposition on Friday, February 21, at Glendale's University of Phoenix Stadium, 1 Cardinals Drive, where you can pick up helpful pointers on anything from javelina hunting to bass fishing. Okay, so that's not terribly broad, but, hey, if customizable firearms and turkey hunting lectures are your can of worms, then you'll be in hog heaven. The expo opens at 10 a.m. Admission is $12.
