As you may (or may not) know, I spend an inordinate (today's REALLY BIG word!... :D...) amount of time exploring the highways and by-ways of California, and the surrounding States, by air, in my various, light aircraft.... :-*....
But every now and again, (like proper Pilots.... 8-)...), I get my Sectional Charts* out, study them for my particular region, after reading my manuals for details regarding flying in and around; "Controlled airspace", etc, (as you do), and noting the areas on the chart that I am presently flying in/towards, I am often surprised that those lovely Chaps and Chapesses in Air Traffic Control actually let me sit in my little Cessna 150 Aerobat, let alone actually take to the air in it.... :o...!
All those multi-coloured, Magenta, Blue, Cross-hatched circles, etc, extending around most of the countryside (and me!) means that most of the time I shouldn't be there!.... :'(...!
Its a scary World, inside a Sectional Navigation Chart.. :o..!
...trust me... ;)....>>>
