I mean...
I guess the way you put it, I wasn't just looking hard enough...
There's actually 93 octane all over the United States as well so I just decided to drive all the way back to the East Coast to get 93 octane.
I just was lazy and wasn't driving far enough.
Shame on me for expecting something simple like gas to be conveniently located.
True, there are "93 octane all over the United States". After several road trips across this country, I do see more 93 octane available over there though.
No "Shame" in making mistakes or errors as I'm sure all of us have made mistakes (I know I have). As mentioned, I've made mistakes on this site and have taken ownership of it by letting the person that corrected me know that it's my bad and thanked him/her as well as apologize to him/her when needed.
What's important is we learn from our mistakes ...Sometimes that's the best way to learn (learning from our mistakes)...because it sticks more.
