Standing in a 10m-deep well in the middle of a bright day you will see a piece of night sky, with stars and all, when you look up
I have trouble believing that. Light scatters in the atmosphere; it's not just coming at you in straight lines from each source. Standing in a well doesn't change the fact that the bright, scattered light from the sun or terrestrial sources will reach your eyes and make it impossible to see faint objects. Reducing the amount of peripheral, direct light will improve the situation, but I doubt it will have enough of an impact to be noticeable, and certainly not enough to see "night sky, with stars and all" on a sunny day.
How does he deal with the firearms laws in the state he's traveling to?

Thanks for the good times, Athens/Acropolis. /Is it sad that I still remember my old address?
