@JGoldman10,
I have never been to Guam. Additionally, I have never done merchandise postings on YouTube. Come to think of it, I've never posted anything on YouTube other than an occasional comment when I've liked a video.
There are perhaps many reasons why it is done. Contact a few of the persons who do this and ask them.
Never been to Alaska, either. Although I did make a random phone call to Ketchikan once on a Saturday afternoon. I asked for a randomly named person and to my surprise, there was a person there with such a name. I had to wait until they located him and he came to the phone. This was in the 1980s when I would drink too much and do strange things.
I have however been to Arkansas during the summer. One timet I was there on July 4th (Independence Day). Just past midnight (at which point it was July 5), the temperature was a roasty 100° along with high quality humidity. Why is this important? Because it is.
Now, aren't you glad I gave you this exciting tale?
Admit it. It took your mind off of other things which are stressing you.
